Bloody mucus

Danielle
So I've never had a consistent period, EVER! (My dr suspects PCOS and I have hypothyroid.) I started Dec. 26 which is right on time compared to my last period. The first day it was very very light in the amount but darker than normal. Then the next two days it was heavy and very dark red. Yesterday was suppose to be my last day but I've had stringy brown pieces and now tonight it's almost like a very thick clear discharge with medium red here and there mixed in. I'm just concerned and yes I plan on seeing my dr but has anyone else experienced this??
