Soooo me and my partner had unprotected sex about two weeks ago and he busted a nut inside me. We went to planned parrenthood the following day and asked for a plan B. I was told that if I were to take it there was a 15% chance i could still get pregnant because I my body weight was not were it suppose to be at. Or something like that .. to be honest I forgot.. ANYWAYS so yeah Ive taken BC in the past and I'm always just a day or two late on my period.. but this time I'm 4 days late..about to be 5. I haven't gotten any cramps or nothing to be feeling my period coming. Soooooo my question is would it be possible to be pregnant even after I took the BC?
