I have had sex a number of times, but I have had my period each time now(3times). Every time we have had sex we have used a condom  and I am on the pill but I'm very bad at taking it at the same time everyday. Haven't had sex for a month and got my period yesterday. I am just still worried about it because online it says you can still have your period and be pregnant. I am 16 and it would be a disaster and I have decided not to do it again until I'm older but still worried... could I still be pregnant?
