Help! - Recently quit Birth Control

I have been on birth control for over 10 years and had irregular cycles before I got on the pill. I came off birth control exactly 1 month ago and got a positive ovulation test 2 weeks later. I am now 15 DPO and no sign of AF and negative pregnancy tests. Glow predicted that I was supposed to start AF yesterday.

How long did it take your cycles to regulate after coming off BC? My husband and I are TTC but I am so discouraged thinking that my cycles might still be irregular. Any tips? Advice?
