3 days late with pinching lower abdominal feelings

I average a 25 day cycle. This is my first month of OPKs and I had 2 different times were I believed them to be positive. Once on CD 11 and then on CD 15. I am currently on CD 29 with no period symptoms. I have had lower abdominal pinching recently and light pink EWCM a couple days ago. I have tested properly and get BFNs. Does this sound like AF may still be coming or could these be a chance I get my BFP soon? Thanks for any helpful advice!
