Britt I think it could be left over still. Did you go for bloodwork to track how levels are going down?
I still got a faint bfp after d&c in December and spotted for the most of 42 days I hope your body will be better soon hun. I also had 2 surges up to ov, but never actually ovulated and my first period was light. Only the second one was heavy and felt like a good clean out.
I hope it's a new one for you. Yes, we do cling to almost everything. Xx
