No AF but 2 BFNs 😔

Mallory
Okay ladies, here's my dilemma. I [thought] I ovulated on the 9th, so my husband and I baby danced on the 8th and 9th. AF was supposed to be Tuesday the 20th. Still no AF.... I tested on the 18th and also today....both BFN. So since AF has been late, Glow changed my LAST ovulation date to the 13th, which we also baby danced on that day. Both tests were with blue dye (I hear that sometimes makes a difference) but I am also only one month off birth control. Is it possible it is still in my system and AF is just trying to regulate? Wishing I saw BFP and even had some symptoms I chalked up to pregnancy. But I think I just have wishful thinking. Thoughts?!
