I am starting a ovulation kit

Carrie
My husband andI have been ttc now for 9 months. I had thyroid cancer and a full removal along with my parathyroids in my 20s. I have been cleared by my endo and obgyn docs. My thyroid meds are on the slightly elevated side to keep cancer cells from ever returning. I am afraid I do not ovulate regularly each month so I am starting to track with kits for the first time this month. I also have a dry cm issue so I am trying pre seed lubricant to help. I never thought it would be this hard to conceive but In my twenties I was fighting a very different issue and was unable to conceive. Then again I never had cm issues in my twenties. Is anyone else going through anything similar in their 30s?
