How to know when you are pregnant

How do you know whether you're pregnant or not? If you've been trying to get pregnant, there are a few ways to find out whether you're pregnant.

Early pregnancy symptoms

If you notice one or more of these symptoms, it might be an early sign of pregnancy and a good idea to take a pregnancy test.

•      Late period
•      Extreme tiredness
•      Need to wee more often
•      Nausea
•      A metallic taste in your mouth
•      Sensitivity to smells
•      Tender or sore breasts.

How do pregnancy tests work?

Pregnancy tests work by detecting one of the key early signs of pregnancy: a hormone called human chorionic gonadotrophin (hCG). This hormone is only made when a woman is pregnant.

Traces of hCG can be found in the urine from three to four days after implantation, but the concentration needs to continue to build up to a level at which the test can detect it and give a positive result. The best time to take a pregnancy test is from the day that the period is missed. 

Where can I get a pregnancy test?

GP pregnancy test

These tests are either free or a small fee is charged.

You’ll need to take a sample of your urine in a clean container (you can get sample pots from your GP’s surgery). The best time to collect a urine sample is first thing in the morning. This is because levels of hCG will have built up overnight.

If the urine sample is tested on the spot, you probably will be given the result after just a few minutes. You may have to wait up to a few days for the pregnancy test results though.

Home pregnancy test

These tests are available to buy from chemists or supermarkets and enable you to find out if you are pregnant in private after a few minutes.

The tests are considered to be quite accurate, although it is essential that you follow the manufacturer’s instructions carefully.

Choose a kit that you think will be easy for you to use and make sure that you understand what mark or symbol will appear if the test is positive.

Find out more about taking a pregnancy test.

How accurate is the pregnancy test?

It is important to know that whilst a positive result is likely to be accurate, a negative result may be misleading. Some women have a negative result and test again a week later to find that it is positive.

This is due to the levels of pregnancy hormone gradually building up to a level at which they can be detected. If you test yourself very early on and you have a negative result, you should carry out another test in 2-3 days’ time if you have still not had a period.

If you continue to get negative results and still no period, you should consult your doctor.

What should I do if I am pregnant?

Once you get a positive pregnancy test, make an appointment to see your doctor or a midwife.

Tell the doctor’s surgery when you are making the appointment that you have had a positive pregnancy test result as you might need a longer appointment.

      Hi guys... I'm 20 days late but I have no pregnancy symptoms. I tested when I was 10 days late and the results was negative...I had a miscarriage last year August... So I'm a little scared to buy a test.. I have a regular cycle of 28 days..I'm slightly Constipated as well. And i have this white creamy discharge. Yesterday I had cramping and felt like I was going to get my periods but nothing happened. I don't wanna get my hopes up and I can't bring myself to go buy a test.. Has anyone experienced something like this?

      Had 2 day bleeding 23-25th of feb and my period was due 5th of March and no sign of it. 3 days late and still getting negative test result. Getting back cramping too but no sign of period and experiencing headaches. If I am pregnant I think I probably conceived nearly 2 weeks ago

    • By Tina (not verified) on 8 Mar 2019 - 14:33

      I had unprotected sex on 13th Jan just before fertile window 14-19th started spotting 24th Jan. My periods are normally regular every 27-28 days. I had a faint positive on 2 different hpt on 1st and 2nd feb. I then had a light period with no clots which was 4 days late on 3rd Feb. my period is normally 5 days but bleed for 6. I then had spotting for 4 more days. In between this time I made an appointment with my doctors on the 5th feb who done a urine test and said could not be sure and thought it could be chemical pregnancy. I am now Day 34 of cycle and normally get cramps before period is due but have had nausea for past week, and extreme fatigue, could I be pregnant?

      Hi - Thank you for your message.
      If you are having unprotected sex and your period is delayed, you should carry out a pregnancy test. If it is positive - you should see your GP for early pregnancy care and referral. If the test is negative you should also see your GP to be checked as to why your period is delayed.

      Me and my boyfriend had sex on Jan 15,16,17 lol wild days. I started bleeding Feb 2 I usually come on 3rd of every month and my periods usually last up to 5 days. But on the 2 of feb I only was bleeding for 2 days, first day I seen a blood clot hanging from my tampon after that it was really light pinkish and brown so I just put a pad on to test my flow. It stopped then started again the second day it was a little red with a lot of brown. I took a clear blue test it came up negative. But I have all the symptoms. Now 3 days ago I got out the shower and seen honey looking discharge coming out my left nipple. and I had clear stretchy discharge when I whipped myself. I set a appointment but I got to wait til Friday and I’m very curious of what it might be. I’m only 21 and I never get any symptoms like this.

      2) And if i could be pregnant...
      Am soo confused...

    • By Midwife @Tommys on 22 Feb 2019 - 13:03

      If you are having negative tests then it maybe that your cycle has been disrupted due the abortion last month. If your period does not come and you continue to get negative tests then do see your GP for a review. They can also have a chat with you about contraception and what would suit you best.
      Best wishes

    • By Bec (not verified) on 19 Feb 2019 - 20:00

      I had an abortion on 11th dec when I was 8 weeks pregnant. I had heavy bleeding for 2 weeks after, and then in jan I had a one day period this month I am now over a week late for my period I have done 2 pregnancy tests which both have come back negative. I am very bloated and worried as there have been a few times when having intercourse I have bled. This happened when I pregnant last time but due to tests being negative I'm very confused. Any advice?

    • By Midwife @Tommys on 20 Feb 2019 - 12:36

      Bec, please go to your GP for review. They will refer you on for Gynae review if you are not pregnant and there is no apparent reason for your sudden change in menstruation. Take care, Tommy's Midwife

    • By Midwife @Tommys on 13 Feb 2019 - 12:23

      Hi Jane
      Using your LMP of 23rd/12/18 - you are likely to be no more than 8 weeks pregnant. Please make sure you get your midwife booking appt and first ultrasound scan date(which will confirm how many weeks pregnant you are) as soon as you can. All the best, Tommy's Midwife

    • By Chloe (not verified) on 12 Feb 2019 - 22:22

    • By Midwife @Tommys on 13 Feb 2019 - 12:07

      Hi Chloe. Please visit your GP as soon as you can. If you are not pregnant, you may need a gynaecology review. All the best, Tommy's Midwife

    • By Angela (not verified) on 12 Feb 2019 - 20:07


      I had a miscarriage in december 15th. Then I had a regular period the last week in January, it ended a week later. I wasn't bleeding for a week, my boyfriend and I had sex, then my period started again with a few small clots. Then I stopped after a week again, we did it again, and I am spotting again? What is wrong with my body? It is making it very difficult for me to conceive again. Please advise. Thank you so much.

      Best regards,


    • By Midwife @Tommys on 13 Feb 2019 - 12:20

      i had unprotected sex ón11th dec and tôok a p2 on the same day,we continued doing it using withdrawal method till 15th of dec ,on the 16 i started bleeding until 19 of the same dec,now i bleeded again on 27th of january but my stomach is becoming somehow big,,,could i be pregnant

    • By Midwife @Tommys on 13 Feb 2019 - 12:16

      Hi Nish.
      The withdrawal method is NOT an effective way to PREVENT pregnancy. So if you are not planning a pregnancy, please use contraception.
      You need to do a pregnancy test if you think that you might be pregnant and visit your GP if you get a positive result.
      All the best, Tommy's Midwife

I saw my period on 12 december and had sex 31st of December and saw my period again on the 12th of January which is more than a week late. and ever since my breast feels sore and has increased in size, I urinate more frequently, my temperature higher, and I feel dizzy, but on the 5th this month.

    • By Midwife @Tommys on 7 Feb 2019 - 15:57

      Hi Wendy - Thank you for your message. If you think you maybe pregnant, you need to carry out a pregnancy test to determine if you are. If you are not, I would suggest you contact your doctor for advice regarding the symptoms you are having.

    • By Rita (not verified) on 7 Feb 2019 - 04:25

      Hey i had sex on my fourth days of period i was bleeding before having sex but I suddenly stop to bleed after having sex am I pregnant?

    • By Midwife @Tommys on 7 Feb 2019 - 16:05

      Dear Rita - thank you for your message. It would be unusual to become pregnant on the 4th day of your cycle. However, if your period is delayed, then you should carry out a pregnancy test to determine if you are or not.

    • By Curious (not verified) on 7 Feb 2019 - 00:09

      If you have unprotected sex and think you maybe pregnant it is important to carry out a pregnancy test from the day your next period is due to determine if you are or not.
