how soon is a pregnancy test effective after u have an intercourse?

Question

i am phobic that i maybe! any signs that is seen rightaway after intercourse that shows that you are pregnant?!!

Answer 1

next time your next period is due

Answer 2

No - pregnancy tests are effective from the day your next period should have started and you wouldn't start having any pregnancy symptoms for a couple of weeks when the embryo starts to implant in the wall of the uterus.

However, if you're concerned that you took a risk and could be pregnant, and don't want to be, if you could get to a pharmacy or your GP in the morning and it would be within 72 hours (3 days) of unprotected intercourse, you could ask for emergency contraception (the morning after pill). It's *much* more effective if you can take it sooner however - the effectiveness rates are:

up to 95 per cent if taken within 24 hours
up to 85 per cent if taken between 25-48 hours
up to 58 per cent if taken between 49-72 hours.

Alternatively, you could have an IUD (intruterine device, otherwise known as the coil) fitted up to five days after the unprotected sex (as long as you haven't had sex again since). This would prevent a fertilised egg, should fertilisation have occurred, implanting and becoming a pregnancy. It can be done by a doctor or family planning nurse.

Answer 3

The most accurate way to test for pregnancy is to wait until after your period is due. All pregnancy tests on the market will pick show a positive result, a higher percentage of the time, if you wait until this point.

Most women, who are trying to get pregnant, will want to know as soon as possible and don't really don't want to wait until they are late to test.

The considerations below will help you decide when the best time to test for pregnancy is.

Ovulation, Conception and Implantation
Please remember that every woman is different and the time it takes for the fertilized egg to implant in your uterus wall can vary. A common misconception -note Tanya's answer above!-is that implantation occurs 7 days after conception, but the research findings showed that first appearance of pregnancy hormone, HCG, due to implantation occurred 6-12 days after ovulation, with 84% of the pregnancies implanting on days 8-10 after ovulation. If you don't get a positive pregnancy test, it doesn't mean that you are not pregnant. It could be that you ovulated later than you thought (meaning that conception and subsequent HCG production didn't happen as you calculated) or that, for you, implantation took longer than the average.
A test with the sensitivity of 20 mIU can pick up a pregnancy at 6-8 days past ovulation but the percentage of women who get a positive this early is relatively low. A much higher percent of women get a positive result at 9 or 10 days past ovulation.

The Downside to Sensitive Early Pregnancy Tests
Sensitive pregnancy tests (20 - 25 mIU) allow you to know earlier if your attempts to conceive were sucessful and get medical care as soon as possible, but there is a down side to very sensitive tests.
Unfortunately, 25% of all pregnancies end in miscarriage and many of these being very early pregnancies. If you use a very sensitive pregnancy test, where you test before the day your period is due, you could catch an early pregnancy and end up going on to have your period anyway due to a very early miscarriage. If had waited to test until your period was due, you wouldn't be aware that you had a miscarriage. Some women will find it very hard to deal with this sort of emotional roller coaster.

In Conclusion
If you are familiar with your cycle, and you are emotionally able to deal with knowing about an early miscarriage, testing at 9 or 10 days past ovulation with a sensitive ( 20 - 25 mIU ) pregnancy test can yield a positive result in a good percentage of women.

Answer 4

No, there are no signs. You can only do the test at least two weeks after intercourse, and even then many are not sensitive to detect the pregnancy hormone until later on. Hence it's best to wait until the first day of your missed period

Answer 5

A pregnancy test will accurately tell you whether you are pregnant or not on the day your period is due. As fertilisation never occurs at the moment of intercourse there are no immediate signs.

Answer 6

No there isnt anything that u can actually check straight away with it. You need time for the HCG (pregnancy hormone) to build up in your body. U can try doing a blood test in the first week, but it isnt always detected. Urine tests are more affective if they are done 7 days before or 7 days after your menstrual period.

Answer 7

You have to wait till at the earliest, a week before your missed period.

Depends on the test too...

Answer 8

I would wait 4 weeksand even then the line is very faint

Answer 9

5 days is the earliest some tests will work
ask your pharmacist

Answer 10

Ive read your other questions and my advice to you is to keep away from sex till you have a semblance of an idea of what you are doing.
