Help please!

Makayla

Headaches, cramping, high soft cervix facing kinda backwards, lots of slightly yellow tinged gooey CM, low backache, very emotional, clingy pets and toddler, slight cold symptoms, basically just feeling off. My period is 2-3 days late. Tested yesterday afternoon, BFN! I know I'm not out til AF shows up.

Anybody has this happen and later gotten a BFP? How many days late were you?
