So I’m on the pill and normally I start my period on the second day of my 7 days off, but I haven’t started yet and it’s the end of the 3rd day, slightly concerned, had sex 4-6 weeks ago with a condom as we aren’t ready for kids yet and extra safe incase the pill doesn’t work for me as a contraceptive! I’m 17! The pill since starting regulated my period as they were ALL OVER THE PLACE before I went on! Is there a chance that I could be pregnant? Any advice about anything in general to do with this?...
