Talk to your doctor. If you are still producing milk you may have a high prolactin level ..... Or possibly prolactinoma..... I agree with the other poster that you may need to take medicine to bring your prolactin level down so you can conceive..... However, I would take Dostinex over Bromocriptine. Dostinex is considered more effective with fewer side effects. Bromocriptine made me extremely ill.
By the way, we were also trying to conceive while I was taking Dostinex - took us only one month of trying (I had been on medicine
for a while). I was told I could not get pregnant without taking it.
Anyway, a visit to an endocrinologist could only help. No sense in trying to self-diagnose!
Best of luck!
