PCOS and Implantation bleeding??

Hey all!

I have PCOS and have been TTC for three years now. My cycle is longer, but not irregular. I usually get three days of spotting before my period, but have been spotting on and off since Saturday. It's mostly pale brown with some dark brown bits every now and then. I have never spotted this long before... usually it turns into full blown heavy bleeding by the third day of spotting. Everyone is so different, and I get that. I was just wondering if there are any PCOS ladies out there with ib insight.

Thanks!
