HELP, OPINIONS?

Hey cycle buddies!! I’m having a dilemma and just wanted to see if anyone experienced something similar.

I’ve been on birth control 9 years. I stopped taking it on April 30th, mid pack (I know I probably shouldn’t have done this but I was super pumped that my husband finally said LETS HAVE A BABY!) I stopped the week of ovulation as shown below. I had withdraw bleeding May 3rd-May 7th. My birth control made my period very reliable, I started on the exact same day of every month with no variation, EVER.

I am now 6 days late. Last week during the exact time frame I was meant to start I had all period symptoms for about 5 days which have gone away but no AF. I’ve take 4 pregnancy tests all with very clear negatives not even a shadow or evap of a line.

Has anyone else experienced this after stopping birth control? How long did it take before your period came back?
