My boyfriend and Intercourse on sunday october 25th at around 6:30pm it was unprotected but it didnt last more than aproximately a minute because it was my firat time and it hurt. He didnt ejaculate and there was no pre ejaculation. I was worried all night and the next morning so i bought Next Choice one dose. I took it at 2:40 pm the next day. But about an hour and a half after i took it i coughed it up and im worried i could get pregnant. Am i pregnant? Could i be? Please help im really worried
