I started taking Yasmin this month, I did everything the box said, started taking it on the first day of menstruation, like clockwork everyday... It's now 4 days into my break week and there's no withdrawal bleed and my breasts still feel swollen. Is this normal? When should I expect my withdrawal bleed to start? I live on an island and the local pharmacy ran out of pregnancy tests and don't know when the next shipment will arrive. I only had sex once in the past month!
