See your PCP: There are quite a few things rgat may be going on with you. See your primary care physician who will figure out what exactly is going on with you. Good luck.

Need attention: Need a set of hormons to be checked including your thyroid, fsh and lh.

PCOS: Weight gain and irregular periods may indicate pcos - polycystic ovary syndrome. Hormone blood tests may be helpful, and medication such as metformin or birth control pills may often be very helpful. See your gynecologist.
