What does my baby look like?
Your tiny baby is 2mm, about the size of a sesame seed.
The outer layer of the cushiony amniotic sac develops into the placenta. Its cells grow deep into the wall of your womb, creating a rich blood supply.
Your placenta will give your baby nutrients (food) and oxygen through their umbilical cord.
It has three vessels: One thick vessel carrying oxygenated blood and nutrients to the baby (they won’t breathe through their lungs until they're born - which is why waterbirths are safe), and two thinner vessels that carry blood containing waste-products back into your circulatory system.
The placenta is a remarkable lifeline that also keeps bacteria and viruses away from your baby.
Your pregnancy symptoms in week 5
Pickles and ice cream – all about cravings
Have you been having cravings? Or maybe you’ve taken a sudden dislike to one of your favourite foods? Cravings aren’t uncommon in pregnancy but don’t worry if you don’t get any, because that’s very normal too. Read about the 10 most-common pregnancy myths.
What to do in week 5
Choosing the best nutrition for you and your baby
You might find it hard to believe you are truly pregnant as you are unlikely to have seen a midwife yet, but it’s time to start looking after yourself and your baby. This week we’re looking at food and nutrition in pregnancy.
Your body is working hard to grow a baby but it’s also very efficient, which means there’s no need to ‘eat for two’. You won’t need any extra calories until your final trimester (and at that point you will only need an extra 200 calories a day – about half a sandwich). If you have morning sickness eating small meals often to keep your blood sugar levels steady.
Find out what 200 calories looks like.
Not doubling your calories will also help you manage your weight in pregnancy. Find out more about how much weight you may gain here.
Eating a healthy, balanced diet in pregnancy will give you more energy and ensure your baby gets all the nutrients it needs.
“I used to eat a lot of junk food, but when I was pregnant I took healthy snacks to work instead - fruit, yoghurts and almonds - and I drank a lot of water.”
Nadia, mum of one
Find out more about managing your weight in pregnancy.
What foods are off limits?
Trying to remember all the dos and don’ts in pregnancy – like which foods to avoid - feels complicated, but don't worry, and don't be too concerned if you have eaten something that is on the list, the risk is small. Talk to your midwife if you can't stop worrying about it.
Read our tips to avoid food poisoning.
Vegetarian or vegan?
It’s fine to follow a vegetarian or vegan diet in pregnancy but make sure it is varied and includes all the food groups. Learn more about planning your vegetarian or vegan diet to ensure your baby gets enough vitamin B12, riboflavin, iron, zinc, calcium and iodine.
Cutting down on caffeine
Too much caffeine is harmful to a growing baby so it’s important to limit your intake to 200mg a day now that you’re pregnant. You might be surprised to learn that caffeine is not just found in coffee, but also in tea, chocolate and energy drinks! Decaffeinated tea and coffee, fruit juice or water are all good choices if you are used to drinking a lot of caffeinated drinks. Use our caffeine calculator to see how much caffine is in your diet.

Hello. I have been having pregnancy symptoms for the last 2 weeks. I had a period but only for 2 days with some spotting. I took 3 at home pregnancy tests all which came back negative and had a blood test done which was negative. Yet the ultrasound shows a gestational sac. Could I still be pregnant? Has anyone had this happen to them?

i had the same case, but i wasn’t pregnant. usually the blood test is correct.

Am 5 weeks pregnant i had some brownich discharges when i wipe only, went to doctor and saw gest sac but no heart beat, she gave prgesteron injection for 3 days and stay at home rest
I also have mild pain which i cannot localize where that comes and goes
By NS (not verified) on 25 Jul 2019 - 21:37
Your doctor should not be giving you progesterone injections as it has been shown that it does not reduce the risk of miscarriage.
Mild generalized pain can be a good sign of implantation and uterus starting to expand.

8 days ago I took a pregnancy test and it came up positive. I took two more and the test showed that it was 1-2 weeks from conception. An app I have says that I would be 6 weeks and 3 days since the first day of my last period. I went to the doctors to confirm and she did a urine test which also came up positive she also got me to have a blood test which I still have not got the results from yet and I have a scan booked in for 2 weeks from now. At that time I found out I was pregnant I had tender breasts and lower abdominal cramps but in the last few days it’s like as if all my symptoms have gone away which is frightening. I have not experienced any bleeding but is this a sign that something could be wrong? I’m not sure if I’m being paranoid or if I should go see my doctor.
By Sandra (not verified) on 21 Jun 2019 - 12:35
Hi , I have the same i think experience. A week ago did pregnancy test it came up positive. 1 week before test I had all right symptoms but after test was done next day all signs disappeared. A week later started to have a light brown discharge and now I am waiting for tomorrow because my blood results will be back. Fingers crossed everything is fine with you and me too!

I also found out that i have retroverted uterus. I only feel bloated and breast tenderness.. no vomiting or neusea. Whenever i pee, i feel abdominal pain and it goes away after i lie down for a while. No bleeding but occasional crapms and back pain. I was given 2 more weeks to repeat the ultrasound.

Firstly I am so so sorry to hear your sad news, my heart really goes out to you.
You probably have a blighted ovum, A blighted ovum is a pregnancy where a sac and placenta grow, but a baby does not. It is also called an 'anembryonic pregnancy' as there is no embryo (developing baby). Because a blighted ovum still makes hormones, it can show up as a positive pregnancy test.
Try to remain positive but be prepared that this time it may not happen for you.
I wish you all the best I really do x
By Geng Enrico (not verified) on 19 Jan 2020 - 09:17
Im also 5 weeks and 5 days pregnant i also ask that case to my ob gyne. That it is normal that the 5 weeks old cannot detect the heartbeat. And he answred it is normal that an as its early age of the baby or as 5 weeks old the baby cannot detect the heartbeat. 10 weeks of gestation or 12 weeks can really sure heard the heartbeat of the baby. So dont feel sorry. Or sad just wait for another couple of weeks to heard the babies heart beat.

Looking for some comfort . I was slightly bleeding and went for internal and external ultrasound two days ago but nothing was detected not even gestational sac. I am now bleeding on and off brown and slightly red but not too heavy as it only shows when I wipe not enough to reach the pantyliner. My hcg levels were 1500 Wednesday and going back tomorrow for more. Absolutely praying my baby is safe! I know some women bleed but I am so scared. They didn't seen anything has anyone experienced not being able to see anything at 5+2?? Please help

By Midwife @Tommys on 20 Mar 2019 - 10:43
If you have still not seen your period, and your pregnancy tests are negative, then it is a good idea for you to visit your GP. They will review you and refer you to a gynae clinic if they are concerned about your symptoms. Take care, Tommy's Midwife

I can't stop thinking and browsing for the same topics everyday. I have 3 children , before the last born I had an ectopic pregnancy so I considered my last born lucky. I have recently tested positive for pregnancy with two test and booked an immediate scan which showed nothing at all except for the thick lining and cysts . The tech booked another scan in 3 weeks and said it might be too early and asked if I had irregular cycles which I had . I am worried I am getting out of my mind. My partner said I must be positive but I am scared of another ectopic. I have only felft hot a lot and used to urinate a lot and constant hunger as well as my breast was a bit sensitive nipples felt like as if a razor was over it but it's all gone. Nipples and breast don't feel anything. No vomit and nausea but with all my pregnancies I had nausea and vomiting. I just don't feel pregnant although I feel bloated and gassy. I don't have pain nor spotting. I have had wet panties like watery discharge but that is all. It seems like it stopped as well. I am only due for second scan on the 22 March I am worried sick. Any advice please?

It sounds like it would be a good idea to speak with your GP for a review to check for any underlying medical cause of your symptoms.

Hi Michelle, how did your 2nd scan go? I'm in the same boat as you and cannot focus on anything else. I had my first ultrasound today, and the gestational sac and yolk sac were present but not the embryo. They said I am anywhere from 5.5 weeks to 6 weeks but have to wait 2 more weeks for another ultrasound. What did you do pass the time?

Hi, am 26yrs and this is my second child to have.
I had my period twice in Dec 2018, 6th was about 3 day and 28th was also 3days .which is making me confused about this pregnancy.
I was feelings guilty of being pregnant especially abdominal pain and was also having some infection. On the 7th January 2019, I went for tests including hcg...the hch came negative unlike the infection it was reactive. I was put on medication for the reaction and some pain tabs. I took all my medication but the abdominal pain still didn't go away.
On the 24th January 2019, I had a home test and it was faintly positive. I repeated the test on the 27th again and I was more clearer. I went for an ultrasound on the 28th but nothing was found. Am confused pls help me understand off course am going for another scan in the next two weeks. Thanks

Hey this is my first pregnancy and I went to my OBGYN last week and she did her test for closing of the cervix and all. I did an ultrasound just minutes after but it was too small to be done on my tummy so the probe was inserted and a sac was seen but I was told there was a little bleeding but no alarm. I started bleeding the next day with some cramps and called my doctor and she said it was normal becaue it could be implantation bleeding but then it continued for 3 days with period-like cramps. The bleeding and cramps stopped but now I'm not sure if I'm still pregnant or I miscarried, doc says I have to wait 2 weeks before they can tell anything. Could the bleeding have been because of the insertion of the probe?
By Midwife @Tommys on 3 Jan 2019 - 11:57
You will have likely been seen now and I really hope your pregnancy is continuing and all is well. The insertion of the probe would very unlikely be the cause of the bleeding you experienced, it sounds more like an implantation bleed. I hope things have settled down now and you are being well supported.
By Jossy (not verified) on 6 Dec 2018 - 07:34
Am five weeks and four days pregnant. I went for an abdominal ultrascan and only the gestational sac was detected but no fetal found non cardiac activity seen. Am total confused
By Midwife @Tommys on 7 Dec 2018 - 16:45
I am sorry to hear that you are experiencing an anxious time in this pregnancy. It is difficult to know at the moment what is happening, and I would think that they have booked you in for another scan. At 5+4 gestation, it maybe a little early to be able to see a heartbeat so they need to wait until your baby is a bit bigger before they can see a heartbeat. If you have any pain or bleeding then do see your GP.

Hi, am 5weeks gone and my breast suddenly stopped feeling tender, am not on any prenatal vitamins yet and I dnt know if that is the reason why. Should I start taking the vitamins now to replenish my body? Please
By Midwife @Tommys on 26 Nov 2018 - 11:30
No, Multi vitamins are not routinely recommended in pregnancy, but we do advise to take folic acid and vitamin D.
Otherwise just try to maintain a healthy balanced diet and avoid smoking and alcohol. Take care
By Holly (not verified) on 23 Nov 2018 - 23:51
Hi, I'm 5 weeks pregnant and my first initial midwife app wouldn't land until Jan now due to dates midwife is at my surgery, however I had a miscarriage in May and I feel very anxious with this pregnancy. Do you think I could be seen a little earlier for my first midwife app?
By Midwife @Tommys on 26 Nov 2018 - 11:27
Hi Holly, Keep following our weekly advice for early pregnancy including maintaining a good diet, stopping smoking and drinking and taking folic acid. There is no harm in asking whether your appointment can be brought forward but if this isn't possible, your blood tests and scan should be arranged by 12 weeks and your midwife will arrange anything else as soon as possible.
