Growing cycles?

Kayla • Married & we had our perfect baby boy on 03/21/2015, Pierce Huntlee. He was 7lbs 10oz, & 19.5 in 💙
I've been off birth control since Janurary. I was on nuvaring for 6-7 years. Since being off my cycles have been 30,26,34, now currently on cd36 with no af and bfns. Anyone else have cycles that see. I had a regular af while on bc, usually 29-30 days, but I had to take my nuvaring out to have my period. Anyone else have cycles that seem to be growing? Does this seem normal after birth control? Thanks ?
