"took plan b on october 28th after the condom slipped. i took it 3 hour after the accident. i got a period 2 weeks later it started off light but then was normal and lasted the usual amount of days except i didn&#039;t have cramps like usual.. this was on november 12th and i have not had a period since.. i am so worried. i took a pregnancy test on november 28th and it was negative. i was expecting my period on 12th of december but it never came.. i started getting cramps that day like it would come and i have been getting them ever since but nothing.. i&#039;m terrified. i am in no way ready to have a baby. is this normal?? i don&#039;t really know if it worked for me.. i thought it did but my period this month never showed so now i&#039;m not sure."
