Possible to still be pregnant?

Hi ladies!! My AF is NOT welcomed on 12/19! Last night I pink/brown tinged CM (I ovulated around 11/27 and already has pinked tinged CM on 12/4 so I don’t think it’s implantation— I have 37 day cycles).. I woke up this morning with a lot of cramping.. my CM as of now at 8:30 is a tiny bit pink but also creamy.. Has anyone ever had these symptoms and still gotten a BFP???? Thanks for your input!! I really appreciate it! 😊
