PCOS ?

I missed my period for 4 months and put on 60 pounds originally but was able to lose about 20 of it .My periods seem to have gotten worse as they years passed ( More painful cramps and mood swings). I tend to have more hair than other girls like on my face, my arms, etc. My periods aren’t irregular anymore though. I got tested for any thyroid issues in 2017 but it came back negative . I’m not sure if I may have PCOS or not ?
