So I have the kylenna as my birth control method. I’ve had for about 9 months and at first my periods were absolutely horrible. They were heavier then before and lasted way longer then normal. Last month I had a monster period. It was the worst one yet. I can’t remember exactly I had it because my periods got all messed up when I got on birth control. I do have sex at least 3 times a week with my boyfriend and I haven’t got my period this month. I’m 17 days late. I know I have birth control but I’m just worried! I haven’t had any abdominal pains or cramping but I have been super nauseous for the past week.
