Period/ovulation after pill

Was on the pill for almost 10 years .. stopped at the end of feb (end of pack) got my “withdrawal bleed” regularly at the end of the pack and then no period at all for a little over 3 months ! Made a appointment at my gyn and the DAY BEFORE my period finally came on June 6th which lasted for 5 days .. according to app should be entering my fertile window coming up this week fingers crossed ... have a lot of you had trouble ovulating once your period returned after taking the pill ? I’m worried that I’m still going to be irregular for a few more months .. been using clear blue to track but just wondering others experiences in similar situations
