PCOS?

la
Hi there!  I've been TTC and off the pill since July and have had irregular cycles of 45,67,54 days and  now currently on day 57 with no end in sight. I talked to a resident at my doctors office because before I went on the pill I would go months without a period and then it would be super heavy for 1 day so I was worried it was happening again. He sent me for blood work (which came back "normal") and referred me to an endocrinologist. She wasn't overly helpful and said "I might have PCOS as I have long cycles and I complained about acne (I don't have acne I just told her I had two pimples which was unusual for me) she sent me for blood work and that was normal again. I had an ultrasound done and an internal done and now I don't go back to her until mid April and that's when she will start meds she said. Anything to do or try in the meantime? One of my biggest concerns is my weight gain since going  off the pill. I just want to eat everything. I'm 159lbs and she suggested I lose weight. Sorry for the long post!
