You have explained almost exactly what happened to me. I was a Sophomore in High School when I got a pituitary tumor. I didn't have a period, my breast lactated,pretty much my body thought it was pregnant but it wasn't. I didn't have a period for about 8 moths or so. I was put on Parlodel for about a year. They check my prolacten level throughout that time and it was always high. Once my prolacten level was normal they did another MRI and the tumor was gone. I started having a period again a couple months later. The doctor explained the same thing to me. "that is had been reduced to excess cells.

I am now 23 and have 16 month old twin boys. They were natural twins. I did not take any fertility drugs.

In the last 4 weeks I have been having severe headaches so I went and got a MRI done. They told me today that my pituitary tumor has returned.

I agree that a good endocronoligist is very important to have. Good Luck to everyone and hang in there. :-)
