Letrezole

Jennii

So, I recently found out that I’m not ovulating and I have a nodule on my thyroid gland. Doctor started me on Letrezole. Before I found out I was not ovulating, I would get positive opks on cycle day 18 and on. This is my first cycle taking Letrezole and on cycle day 13 I got a positive opk. Has this happened to anyone? It’s the earliest I’ve had a positive opk. I’ll be getting a progesterone check next week to check if I did indeed ovulate.
