I had unprotected sex 6 days ago. He didn't finish in me or even come close to finishing in me, and I am not on the pill yet. A stupid decision, I know. Anyway, I took Plan B 36 hours later. A couple hours after taking it, I had some light pink discharge. The discharge has stopped but since then I've had some light cramping and my breasts have become very sore, I've had some minor, short-lasking headaches and I've been rather tired. I've read that these are side-effects of Plan B, and I know Plan B doesn't work on everyone. I've been expecting my period for a couple weeks now, and it's rather irregular. This was my first time having unprotected sex, and I'm terrified that I might be pregnant. Has anyone else had this happen, and are my chances of pregnancy high? Thank you!
