Yesterday (November 23) I had unprotected sex, and and well he ejaculated in me. I'm not birth control, so I sorta freaked out. About 10-11 hours later I took the Plan B pill. I haven't had any of the symptoms that it said I would have, but it hasn't been 24 hours yet so I don't know. Also, I had sex with him the day after my period ended. Not sure if that will increase my chances at not getting pregnant or not. I also weigh 175-180. I read that the pills weight limit is set to 160 and under. Will that affect it's affectiveness?
