TTC after Mirena?

Mikaela • 18. OH. ttc buddies can kik me @ HeyThereMikaela. Baby dust to all💕
I had the mirena IUD for 2 years after a MC at 15. I got it taken out in August and have had a pretty regular 28 day cycle since September. I haven't gotten any positive OPKs, so I'm worried I'm not ovulating. How long did it take you to get pregnant/Ovulate after you had your IUD removed?
