Two days late

Truly Blessed • 👼🏼July 2017 👼🏼 June 2018 . Rainbow 🌈 baby born 2/17/20

I’m two days late . I didn’t have my pms symptoms this cycle which is usually cramping a week before AF. . I keep getting this off and on light cramping sensation feeling like AF flow is coming . When I wipe I get this clear slippery discharge on the the tissue (sometimes). I tested on Wednesday and got a BFN. Any ideas . I’m 16dpo
