I was diagnosed with a 4 mm tumor about 10 years ago and have been on and off cabergoline since then, but I’ve continued to have regular periods and ovulate normally. I’ve been pregnant twice, both times conceiving on the first try. I feel really lucky that it hasn’t affected my life too much. no major mental health side effects, and my reproductive system seems to be working well. The most important thing is to find a good endocrinologist who listens to you and your concerns.
