TTC After Mirena

How long did it take for you ladies until your body started getting on a regular cycle again? I had my mirena removed early January and have had a period every month but they’ve all been off from the previous and it’s hard to track my ovulation days when each period is 4-7 days off from the previous one. Also I feel like I ovulate for 2 weeks not sure if thats normal or not? First baby I didn’t track anything because I was on BC and had an oops baby so sorry if these questions sound dumb lol.
