TTC after Skyla IUD

Hi! So on the 14th, I had my Skyla removed. On Skyla, I never had a period— just random spotting every other month or so. Two days after getting it out, I got what I thought was my period for 5 days. I just used that as my first cycle on my app and I know it’s still super early— but has anyone had any experience with this? My husband and I are TTC #1. I’ve started using OPKs but not really sure if I’m using them right or if my body just hasn’t adjusted yet. Thanks y’all!!
