Ovulation

Hey ladies, was hoping for some advise. I have stage 1-2 endo with 2 laparoscopies. In July 2019, I stopped birth control (after 10 years) while on the pill, I wouldn’t get a period due to all the pain and discomfort. We are currently trying to have a baby since last month. Last month I ovulated after cycle day 10. Then when my period arrived it was completely different than the rest I’ve had since I stopped the pill. I spotted Wednesday-Saturday and then Sunday-Tuesday heavy flow and then Wednesday it was gone. Now I’m on cycle day 15 and I haven’t ovulated. Cycle day 11 Glow said I was about to ovulate and to start trying and now every time I take a test, the line gets fainter and fainter. Google says you can ovulate 11-21 days after the first day of your period. Has this happened to anyone?
