Going to the Doctor for Diagnosis

Hey ladies! I have a quick question.

How were you diagnosed with PCOS and were there any symptoms you had before diagnoses that lead you to seeing a doctor?

I don’t know if I’m overreacting or anything, and I know I’m still young. My period has been over a month late, and even though I’m irregular, it’s never been this late. I have a history of ovarian cysts, starting when I was 13. Ive had 3 in the span of 5 years. Each one ruptured. I’m debating about going to see my gynecologist or not to see if he thinks I could have PCOS or anything wrong in general. I know what I’m feeling could be a multitude of things, but i just have a suspicion something’s not right.

Thank you in advanced!!!
