What does my baby look like?
Your baby is about 12cm long, and weighs roughly 150g. Your bump is getting bigger.
If you could see your baby’s tiny face, you’d notice eyelashes and eyebrows starting to grow. And if you could take their hand, you’d see they already have a unique fingerprint. Amazing.
Before this point, your baby’s head was bigger in proportion to their body. Now, however, their body is starting to fill out, and their proportions are starting to even out.
The placenta continues to grow to keep up with your baby's needs. By the time you give birth it will weigh about 500g.
Your symptoms - what to expect
Do you have swollen feet? Suffering from pelvic pain or headaches?
Your waist will start to disappear as your womb moves up out of your pelvis and your bump becomes more noticeable. If you've been pregnant before, your bump may start showing a bit sooner than for first-time mums. Have you thought about keeping a bump diary and taking pictures each week?
How are you feeling?
You may start to feel happier and more confident as your bump becomes more noticeable and you start to feel baby move. Some women and men find that their pregnancy suddenly feels more real when they first see the baby at a scan.
You may also have more energy to enjoy getting out and about more.
However, pregnancy can make worries about money or relationships feel bigger. As many as one in 10 expectant mums feel stressed and anxious.
Pregnancy hormones can often be to blame, not to mention coping with health issues, worrying about giving birth and the responsibilities of parenthood.
If you’re feeling stressed and anxious, or suffering from depression, don’t hesitate to tell your midwife. They are there to talk about your mental wellbeing in pregnancy, as well as your physical health.
Actions to take
Do I need to eat for two?
You may be wondering what to eat, or how much. No matter what well-meaning future grandparents might say - you don’t need to eat for two during pregnancy. Your baby takes everything he or she needs from your body, and will grow well without you taking in any extra calories at all until the last three months.
Once you reach six months, you may need an extra 200 calories a day, which is around half a sandwich.
Suffering from a loss of appetite? Here are 10 super snacks to help your baby grow.
Are you getting enough vitamin D?
All pregnant women should take a 10 microgram supplement of vitamin D each day to give your baby enough vitamin D for the first few months of life. Without it, there is a risk that your child will have soft bones, which can lead to rickets (a disease that affects bone development in children).

Aerobics in pregnancy
Aerobics is great for your heart and lungs and improves muscle strength. If you’ve been doing aerobics, you can carry on while you’re pregnant.
If you’re new to it, tell the instructor you’re pregnant and start with just 15 minutes' continuous exercise three times a week. Increase this gradually to a maximum of four 30-minute sessions a week.
“I exercised throughout both my pregnancies, right up until my due date. I was more tired in the second pregnancy, because I was running around after my daughter, but I always did something active because it made me feel better.”
Anna, mum of two

I have not visited any anti natal and have not used any vitamin supplement is it dangerous for my baby?and when can I go for a scan to know the sex of my baby.
By Midwife @Tommys on 17 May 2017 - 09:22
You should urgently make a GP appointment to be referred to your local midwifery services. (You can also contact your local midwives for an appointment via your local hospitals website) You should have had a booking appointment with your midwife by 12 weeks and your first scan should have been around that time too.
Taking pregnancy vitamins are not vital, but they are encouraged to help give you and your growing baby a little boost to the nutrients that you both need to have a healthy pregnancy. If you decide that you want to take these, they are available from all pharmacy's and supermarkets.
Please take good care of yourself and get yourself seen and booked in with a midwife as soon as possible!

I am 17 weeks, I am very much emotionally depressed. I am not feeling like to do any thing like, go out, wear make up, grooming, talking to family or friends. I just want to stay in my room. As if very thing is colourless. I can not think any thing except my baby my all the focus, thoughts and concentration end on my baby only. I can not understand what should I do. I am a working lady and now a days I am very quite on my job as well as at home :(
By Midwife @Tommys on 12 May 2017 - 10:19
Thank you for your comment. I am sorry to hear that you are feeling depressed. I am concerned that you do not want to go out, talk to family or friends, are not grooming or wearing make-up and just want to stay in your room.
Is there anyone you would be able to talk to about these
I hope by now that you have started your antenatal care and have met your midwife team, also that everything is going well with the pregnancy
It is very normal to want to focus on your growing baby but you should also be able to enjoy your life and the pregnancy.
I would strongly advise you to make an appointment with your GP as soon as possible to discuss these feelings so that they can advise some treatment such as counselling that can help you feel better. You can also contact your midwife as they can also refer you to local support services.
Please do this sooner rather than later to help you start feeling better
I have attached some links with more information that you may find helpful
I hope this helps.
Please do not hesitate to contact us again or call our helpline

I am almost 17 weeks with flu like symptoms the last 3 days . Missedy 16 week midwife appt .
By Midwife @Tommys on 27 Apr 2017 - 09:32
Very sorry to hear that you are feeling unwell. Please remember to contact your midwife team and arrange to be seen as soon as you can. The 16 week appointment is important to ensure that all tests have been done and that blood results are filed in your notes to ensure continuity of care. You may also get a chance to listen to your baby's heartbeat. We hope you feel better soon. Tommy's midwives

I am 17 weeks and 5 days. I've been feeling small movements since the very end of my 15th week; every couple of days they became stronger. The past 3 or so days the movements have been less, and I'm worried. Is everything okay?
By Midwife @Tommys on 23 Mar 2017 - 14:34
Hi , It is probably too early for the fetal movements to have formed a recognisable pattern yet and I am sure that you are aware that many women don't feel any movements until after 20 weeks. That said, you have the option to call your midwife and ask that she/he listens to the fetal heart with a sonicaid (hand held Doppler) for your reassurance. I expect that you will have an anomaly scan very soon which will be a detailed scan of the baby and placenta. This is normally done between 18 and 22 weeks. Don't hesitate to call if you require more information. Best wishes

Always have a headache and tired
By Midwife @Tommys on 16 Mar 2017 - 09:42
If you are feeling constantly tired and have headaches, it is vitally important that you visit a midwife at your local hospital. You may need to take iron if your iron levels in your blood are low, feeling tired can be asign of this.
Having a constant headache can be a sign of pre-eclampsia too, so you may needs blood taking for that too. Please take yourself in urgently to be reviewed on your local labour ward or triage. Please take good care of yourself
