Tracking ovulation??

Me
Hey, which cycle day do you start using opks, I used to do it so early and have been pregnant two times within 5 months and unfortunutly both times I had a mc, I do want to track again, but not to over analysis and become obsessed. So I'm thinking maybe cd12 - cd14, the generic time ovulation accurs, I just don't want to miss it, and pray that it'll be 3rd time lucky for me 💔
