Hi. I'm not sure what's wrong with my cycle, I normally bleed heavy on my 2nd day and my period lasts 4 days, I never missed a cyle ever since I started to menstuate. I am 19 years old. My boyfriend and I had unprotected sex 14days after my period. My period after that came 2days late, it was bright red mixed with clear mucus, had some cloths it was medium flow and it lasted 2 days, the next day it was brown. This month the same bright bright red bleeding some cloths lasted 2 days then brown, this months flow was a bit lighter then last month. Could I be pregnant or is it nothing at all? Thanks
