Went off BC in August. Has anyone had a similar situation?

Naomi • USAF Wife! ♡ Been married for 4 years, 27 & ttc baby #2. DS is 13 months old.
So I went of my pills in August. I had a 35 day cycle the first month of being off them, and now I'm on cd37 of month 2. I went on the pills to begin with because I wasn't having a period. It's been 6 years, I'm about 5 lbs heavier and not nearly as active. Has anyone had their period, then had their period not show for over a month after going off the pill?
