I cant tell if i am pregnant or not :(

I had unprotected Sex janurary 2nd that day my period had ended, it started the 28th. So later that day i took the morning after pill because my boyfriend came in me.Which caused me to have  my period again on the 6 or 7th of Janurary I didnt start my period nore have i started it anytime this month.. I took 3 pregnancy tests and they all said Negative..My step mom its saying alot of stress.. But its freakin me out because i still havent started my period...

My last period started on the 5th of January. I got a positive pregnancy test over a week ago. By now if you were pregnant you should be coming up positive on a test. Best thing to do is wait a week or so and see if you get your period or retest. Plan B is 85% effective though if taken the day after unprotected sex. Most likely its just stress.

I agree, stress before you ovulate can cause you to ovulate late.  I'd wait a few weeks, and if your still worried call your dr.
