Thread: Big Problem!!!

So here are my problems:

#1) I had sex about a month ago (we used a condom), the very next day I started my period.
But now, a month later, I'm a couple days late. I should have started on the 18th and I've had the cramps the past couple of days thinking i would start, but nothing yet. Should I be worried?

#2) I had sex (with the same guy) on saturday and the condom fell off. He says he's sure he pulled out in time, but he was still kinda freaked out. If i start my period today or tomorrow (that takes care of problem number 1) but should i still get the plan b just in case?

Pretty much my question is, if i have sex and i start within the next couple of days, should I be worried. Most of my friends, who have been sexually active alot longer than me, say no and that your period flushes everything out, but I'm still unsure.
