emergency contraception
"Help! I took plan b on October 28th, 3 hours after an incident my bf and I had. I got a period about 2 weeks later on November 12th. It was lighter and I didn't have cramps but still it lasted the same amount of time they usually do. MY PERIODS ARE VERY IRREGULAR. I had a period on July 14th, August 15th, September 22nd. I did not have one in October.. my last period was the one after plan b on November 12th. I took a pregnancy test on November 28th and it was negative. I'm worried sick because I haven't gotten a period this month!! I don't know if plan b worked or not!! I plan to take a test as soon as I can but I'm worried. Is this normal?? "
