emergency contraception
"Me and my boyfriend had unprotected sex the second day of my period. 20 to 24 hours later I took Plan B. I had nausea select days over a week or two then everything seemed back to normal. Two days after I had unprotected sex my period stopped. Plan B works three different ways one of them being telling your body not to ovulate. Well 11 days after my period stopped I was due to ovulate. Plan B more than likely told my body not to ovulate at that time because my period was 9 days late. I'm also overweight by a couple pounds to where Plan B effectiveness starts to fade. I think because I was ovulating close to when I took Plan B it told my body to wait to ovulate. Today I got my period. Thank goodness!!"
