Yes. Please demand that your doctor check your prolactin levels. To do it right you will need to fast and then they'll draw your blood.
I tried for 6 long years to get pregnant and they were about to put me on Clomid when my dr checked my prolactin levels. Turns out that they were through the roof. I took half a pill 2 times a week to regulate my prolactin and I was pregnant in about a year.
