Hello!I'm 17 years old. My period is late and about 5 days I had a nosebleed everyday. I had sex almost 3 months ago and 2 periods since then, and 2 negative pregnancy tests. Now my menstrual cycle is irregular about 2 months it was 30-32 and before it was 28 days. Now is 36 day and period is not showing, I have Pms symptoms but nothing.
