I Have Had A Couple Doctors Tell Me I Have

I have had a couple doctors tell me I have s/s of PCOS and depression. That doesn't surprise me. I have missed my period for the last four and a half months, taken a pregnancy test once a week (all negative). My breasts are very sore, I'm nauseous and sick after sex, have migraines a few times a week, I've been having major cramps in my lower abdomen and crying for no reason. I'd like to chock it up to hormone imbalance due to PCOS but I'm not sure. Anything you've heard of before?
