Doing a pregnancy test

Is the pregnancy test accurate?

When you can do a pregnancy test

You can carry out most pregnancy tests on a sample of urine from the first day of a missed period. If you're pregnant, this is about two weeks after conception. Some very sensitive pregnancy tests can be used even before you miss a period, from as early as eight days after conception.

You can do a pregnancy test on urine collected at any time of the day. It doesn't have to be in the morning. Collect the urine in a clean, soap-free, well-rinsed container. 

Where you can get a pregnancy test

You may be able to get a pregnancy test free of charge from your GP. Free pregnancy tests are available from your local community sexual health clinic - which is sometimes known as a contraception, family planning or GUM (genito-urinary medicine) clinic. Free pregnancy tests are also available at NHS walk-in centres. 

Many pregnancy advisory services also offer tests, usually for a small fee.

You can also buy do-it-yourself pregnancy testing kits from pharmacists. They can give a quick result, and you can do the test in private. A range of tests is available. The way they work varies, so check the instructions first.

How does a pregnancy test work?

All pregnancy tests detect the hormone hCG (human chorionic gonadotrophin) which starts to be produced around six days after fertilisation.

Pregnancy test results

A positive test result is almost certainly correct. A negative result is less reliable. If you get a negative result and still think that you're pregnant, wait a week and try again, or see a GP.

Continuing with the pregnancy

If you're pregnant and want to continue with the pregnancy, contact your GP or a midwife to start your antenatal care. You can use the pregnancy due date calculator to work out when your baby is due.

If you're not sure you want to be pregnant

If you're not sure about continuing with the pregnancy, you can discuss this confidentially with a healthcare professional. Your options are:

  • continuing with the pregnancy and keeping the baby 
  • having an abortion
  • continuing with the pregnancy and having the baby adopted

As well as a GP or a nurse at your GP surgery, you can also get accurate, confidential information (even if you’re under 16) from the following:

All these services, including community contraceptive clinics, are confidential. If you're under 16, the staff won't tell your parents. They'll encourage you to talk to your parents, but they won’t force you. 

If you're under 25 and would prefer advice that's aimed specifically at young people, the sexual health charity Brook provides a range of services for young people. The Brook website contains information on pregnancy choices. You can also email them via the Ask Brook website.

Hi. I'm 17 and I'm worried I could be pregnant. I have taken 2 pregnancy tests and they are both negative. Last month my period was late by a week and this month it's now 1-2 weeks late. Not sure if my body is trying to go to the date my period usually is. I have been feeling sick and have had stomach cramps and I have a bloated stomach. It was my first time. We were careful and used protection. But now I'm starting to worry. Please would you help. Thanks

Hiya really need advice...I had a baby 11 weeks ago from 6 weeks ago we have been ttc....I ovulated (I use tests & calculate) then I was like 3/4 days late for my period....I then eventually did come on was like a normal period but it only lasted 2 days! Since my expected period date I have been testing 1 clear blue digital = negative last week but have also been using the cheap strip tests and I get a faint line on them!? But im not sure what to think? Is it a positive? Is it water mark? Or bad tests? Im super confused :(

Hello
Im currently very confused. My last period was the 11th of april 2014 and I know its probably too early but im confused on whether im pregnant or not. My ovulation days were around the 25th and my partner and I have started actively tryingthis month. But for the last couple of days ive been feeling tired, dizzy, had metalic taste in mouth making things I normally love eating and drinking taste weird. Had like a bruised feeling around my lower tummy. My breasts go between sore and normal. Ive become very snappy and weepy with my partner. And although these signs are common in pregnancy I would have thought that its way too early to be experiencing them. Ive done two test as well, one at home and with my gp and the one at home gave a faint positive line but the one with my gp was negative. Am I pregnant or am I just getting my hopes up?

Normally it lasts 6 days. Had a pregnancy test before my period it came negative. Been having headaches and feel lazy. Do you think I could be pregnant ?

Hi swansborough, you can test now if you are 8 days late, i tested myself 10 DPO, and got a very faint line, i'm 1 day late for my period & this mornings test was alot clearer but still faint, i'm still not that convinced that i am pregnant as i had a miscarriage on the 20th march, so if i am, i would of conceived on the 3rd april, which will make me 4 weeks pregnant, let me know how you get on hun :) x

Hi,
I was on the pill, I believe I may of missed one and taken it a day late, I also had sex while not on the pill a few days before my period was due. My period is lighter than it has ever been before. I've been sleeping more than I usually do, also been getting pains around my belly button. Also been craving some foods and have gone off my favourite food! I have also noticed my stomach has been rock hard at some points... Help?

Hi
I don't know if im pregnant or just paranoid like my mates think i am... Ive had problems with periods since i was 16 and now am 19 nearly 20 in febuary and my periods aren't regular. Ive been on and off the pill since i was 16. Ive stopped tracking my periods so ive forgot when my last one was. Me and my boyfriend have unprotected sex quite a lot sometimes every day but sometimes there is a gap where we don't for two three days. Im just wondering with my unregular periods can i still get pregnant? I keep getting backaches, hungry all the time, sleepy most of the time but i cant sleep at night, i feel sick but its like my body stops itself.
Im going to do a pregnancy test tomorrow

Hi,
I wonder if someone can please help.
I have missed a period and a pregnancy kit test has proven positive with my pregnancy. So if that's correct I am 5wks plus pregnant. This was unplanned.
As I have just started with a new job we are considering abortion. So I went to Family planning division at West Middlesex Hospital in Isleworth. The nurse there took a sample of my urine and tested it. But she claims I am not pregnant and advised me to go to my GP after 2 weeks to get a test done.
Would there be a reason for them to give me this verdict?
All I needed was a referral letter from them.
Please advise.
Thanks

"Pregnancy tests are also available at NHS walk-in centres."

Either this information is incorrect or the walk-in centre in Boots, Manchester City Centre is not aware of it. They clearly say they can not do it unless you are registered as their patient.

I took a digital pregnancy test 2 weeks ago as I have been on Micronor for 3 months with no periods. Although this is common, all literature suggests you should confirm you are not pregnant after 45 days. To my imense surpise the test came up positive (digital so no confusion with lines!). Though this was a bit starnge so tested every two days and every other test came up negative. No signs or symptoms but went to GP who gave me a blood test - also negative. Still no sign of a period. Just letting everyone know that false positives do happen without bleeding or being on fertility drugs.
