Not really sure

Alright so I have a few strange things going on with my body and I'm not really sure what it all is or if any of it is even connected with one another. First of all I get random dark hairs that grow on my neck and chest and even a few around my nipples. I pluck them but they always come right back. Also my period tends to b irregular and I even completely miss sometimes. Last thing I'd about a week after my period ends I get a dark brown mucusy discharge. Does anyone have any ideas?!? This has been going on for a few years
