TTC after chemotherapy and overactive thyroid

Hi lovebugs

I'm a breast cancer survivor who recently completed maintenance chemo Herceptin in July for HER2+. I just turned 34 and have never been pregnant. I recently discovered I've had an overactive thyroid that could have possibly interfered with getting pregnant. We're in the process of getting my levels regulated to hopefully start TTC early next year. Has anyone had success with TTC after chemo and or thyroid hormone adjustment? I'm not giving up hope!!

thanks all
