TCC after IUDs.

After 4 years with the Skyla and Mirena IUD, DH and I decided to TCC. My cycles with the IUD were regular as opposed to very irregular without. My Mirena was removed in November and I’ve been having such a hard time tracking my cycles now, which makes it hard to pinpoint when I’m ovulating. How long will it take for my body to get to some sort of regular cycle?
