I had my period september 18th got off the 23rd or 24th and had unprotected sex the 24th, 25th, and the 26th. Also on the 27th and 28th. I took plan b the 24th after the first time cause we freaked out. After that, we had a discussion and decided we wanted to have a baby. After that we had unprotected sex almost every day. Yesterday as in September 30th (when it became midnight for the 30th) I started brown/pink discharge then when I woke up it was bright red and heavy like a period. It does not smell like a period and it does not feel like one, I could be wrong though. I've researched for hours. Some women said that it could be heavy implantation bleeding or it could be my early period. I also saw that plan b only works for the one time you had sex and then took it. So could i be pregnant from all the other days? Please help and let me know :/ it's greatly appreciated.
