I have been taking yasmin birth control for about 2 months now. Im on the second pack and started the "reminder pills" on wednesday of this week. I have taken my pill everyday mainly at the same time( maybe a couple hours of somedays cuz of classes). Last month I got my period on the second day of the reminder pill. This month I had sex with my boyfriend but we always use a condom. I havent started my period yet this month. But I have feeling like I am going to have my period. The slight crapping acne and bloating. Do I have anything to worry about? I heard that some women experience no period when they are on the pill. How do I know if this is the case for me or not? I also took a pregancy test yesterday and it was negative. Did I take it to early to tell? Any answer would be great thank you!
