Dermatomyosistis and pituitary tumor

Carissa
I've had a small pituitary tumor for over 17 years and was diagnosed with Dermatomyosistis 2 years ago. I stopped taking birth control 6 months ago and for the last 2 months I haven't gotten my period but I'm not pregnant. This is such a bummer and I'm afraid my next step is to see a fertility doc.
