Avid test takers! I need help

Desiree

Has anyone got a negative before there missed period or even after? What is the longest length it took for you to get a positive.

Since I've been off the pill in October I started counting my cycle days & I am back & forth between 28 & 29 days. Last cycle was 26 days which was weird. I tested mid day on cycle day 28 with a clear blue digital test & is said not pregnant.

I am going to test tomorrow morning, I would say with my first urine, but I have been peeing so much, 3 times in the middle of the night with full bladders so it's going to be hard. Tomorrow morning will be cycle day 31.
