Went to ER for some very link pink CM (had miscarriage before so I’m nervous) and saw babe measuring on track and HB of 151. I’m still noticing when I stick my finger up there my CM has a light pink tint. Not even enough to get on toilet paper but wtf?! Why is this happening. What are chances everything is fine after seeing babe but still having this pink CM?
