Need advice

Hi everyone, recently I have been having irregular periods and I’m not sext active, I recently been to the doctor and told him what’s been going on with them and that I’ve had a small cyst on the outside of my vagina.

I have to get bloods and a scan done to rule out any other problems but he aid he’s almost certain that it’s polycystic ovary syndrome .

Has any body been through this and what was your symptoms of it . TIA
