I ve been taking Primulot N as I get never ending periods. I had sex three days ago, using a condom, and came off my pills three days ago too to see if I was going to bleed to see if I was pregnant. I haven t bled but I always bleed with in 8 hours of not taking primulot. I bled the day before sex, and one gush of blood after sex but not at all after it, which is extremely abnormal for me. Could I be pregnant?
