I have read some women can show signs as early as one week. My mother and I are very similar. When she became pregnant, her first sign was diarrhea for both her pregnancies. It has been about a week since I expect I may have become pregnant. When can I take a pregnancy test? I am on birth control and I don't want to have to wait an entire month to find out in fear the birth control could harm the pregnancy if I am. I believe I might have become pregnant right after my period. Please Help. Aside from diarrhea and tiredness, I got unexspectedly very nausious the other morning but did not vomit.

There are really no early signs, some women claim, but no two women are the same, in most women, the very first sign is a missed period. There is no way to really test till after you miss your next period. The doctor may be able to do a blood test sooner you will have to call and discuss that with them.

Your signs could be a 100 things,
