High OPK but no Peak

I went off my bc in July (nuvaring). Had a short period in August, and then nothing at all for months. I kept waiting, thinking it would happen, and it just didn’t. Ended up going to my gyno and she put me on medication to force my period. Medication worked and I had a period from December 12-16.

I started ovulation testing because hubby and I are ttc #1. I was supposed to ovulate this last Sunday, but have only gotten “high” readings on the clearblue advanced tests for the last 6 days- no peak!

Has anyone else had these problems? I think I’m pretty healthy, other than being a little overweight and currently working on losing the extra pounds. I’m getting frustrated- I just want a normal cycle :(
