Advice Requested! TTC after BC

MHPW

Hello! Hoping to get some advice after TTC for one month.

In February, I got off brith control after being on it for 10 years. I Had my my first period (only lasted a day) in April, and on May 6, I had a three-day period. I began using ovulation tests and reached peak fertility on May 14 via ClearBlue digital response.

Today, according to Glow I’m 7 days late; however, on another app, I’m considered 3 days late.

I’ve been taking pregnancy tests and have only received negative results. Is my body learning how to regulate itself or could I still potentially be pregnant?

Thanks!
