Will I have accurate results from First Response hpt a week after my missed period? I know they're only 99 percent accurate. I got a negative result but I want to know the chances of still being pregnant? I had soar breasts and constipation, head aches, back pain, and an upset stomach for 2 days which made me want to test. I was very freaked out thinking I was pregnant and wondering if I made myself think I was when I wasn't. Please help?

Most women will get an accurate result after a period is missed. However, some women do find that the tests just do not pick it up for quite some time.

What you describe as symptoms could also be due to a period about to start. Maybe give it another week and test again if still no period. It can be that you might skip a month now and then as well. If you still get a negative result, wait until next month and see if your period shows.

A home test should give you an accurate result from around the time you've missed your period. A week after that, you can expect a very accurate result. If you've had two negative tests, then you are almost certainly not pregnant. Conspitation can give you an upset stomach and headaches. Those are not normal early signs of pregnancy.

I am sorry but I will have to seriously disagree. Just because they have two negative tests does not mean they are not pregnant, it means only they have had two negative tests. Some women may not show positive on a HPT for even two or three months for some reason. And false negative is more common on HPT.
