What am I missing?

Chaya happily 💍❤️ttc 👶🏻hopefully soon 🙏🏻

Ok so im currently 6 days late. I took a blood preg test 12/2 and I was neg and I took a clear blue last night also neg. The weird part is and sorry if it’s TMI but I’ve been having fairly heavy CM the last few days. Can anyone explain??
