Hey I skipped two periods with my birthcontrol and I’ve been taking my birth control on time everyday but I’ve had intercourse in which semen got into me. Tomorrow’s gonna make it 4 days into the placebo week and I still haven’t gotten withdrawal bleeding should I be worried and what happens if I don’t bleed during the placebo week? If I don’t bleed should I continue onto the next pack or wait till I do have a bleed.?
