So I got my last period on March 27th. I had sex on the last day on it which was the 31st. On April 12th I think I experienced implantion bleeding. I saw a little pink when I wiped and again the next day.It was only those two times that I had seen that only when I wiped. So my questions are can that I be pregnant and how long until Im able to take a home pregnancy test? Thanks

Any time you have sex, pregnancy is possible. The time to test is 2 weeks after a missed period, using first morning urine.

Alty is exactly right. Watching all these perceived "signs" is really worthless. Implantation bleeding is rare, not a given. There are many reasons women have spotting from time to time.

There's no way to determine for a few weeks whether you are pregnant or not - even a doctor could not tell at this point.
