Me and my girlfriend are quite worried. Until just recently ( about 2 weeks ago) we were both virgins. She has been on an oral contraceptive called diane-35(mostly for acne control) for about 2 months now. On wednesday she stopped taking them to start her period (cycles or whatever). It's been two days and she still has not started her period. We are worried. We use condoms as well (always). Can this happen without her being pregnant? Could she be pregnant? The last time we had sex was on tuesday. Is the morning-after pill still an option? We are young, naive and new at this. Please help!
