Well, last weekend I went out for my birthday & ran into a friend of mine. Long story short I went home with him & we had unprotected sex in which he didn't pull out...several times. I took the Plan B Sunday afternoon (within 12hrs after the accidents) & I started my period later that week (I'm still on my period right now), but I'm completely freaking out on whether I may be pregnant or not. I need some advice. Has anyone had a similar experience?
