When To Test

Given the fact that implantation normally takes place from 7 to 10 days after ovulation - an extremely sensitive test can give a positive test result 1 day after implantation. Most directions say that you can test on the day your cycle is due. However you can test much earlier if you can pinpoint ovulation and possible implantation. I received a positive test result 4 days before my menstural cycle was due.

A False Negative

The chances of receiving a false negative test result is greater than that of a false positive. The reasons for a false negative are that your body may not be producing enough hCG for that particular test to detect. Some women have gone as long as 17 days post ovulation before receiving a positive home pregnancy test result.

False-Positives?

If you´ve received a false positive on a home pregnancy it is one of two things. 1. The hpt was faulty.
2. You were indeed pregnant and suffered an early miscarriage (chemical pregnancy) - one that occurs around the time the menstrual cycle is due.

Testing Advice

When doing an HPT, make sure that you discard the test after a specified time. When I was doing a HPT, I waited 5 minuts after the time stated and it came up with a faint +ve. When I went to the DR to confirm the pregnancy it was -ve, what I had actually seen was the evaporation line. So PLEASE PLEASE don´t be like me, always follow instructions carefully so that you can save yourself heartache.

Cheap Brands

Are cheap/generic brands of home pregnancy tests any good? Yes, a lot of physician´s offices use these generic brands. Why pay more for a home pregnancy test when the cheaper tests are just as good.

Which brand?

There are many different brands of home pregnancy tests out there. Which brand you choose depends upon your preferences. Some brands are the one-step type you urinate directly on - others are cassettes which require the use of a specimen cup. Each brand differs on the sensitivity ratings - some you can test earlier than when your cycle is due - others you may need to wait until the day after.
