PCOS? ..... or something else? Help!!!!

So background I had my son almost 2.5 years ago. We started trying again for baby no. 2 in January 2018. Previously I was on birth control which I stopped taking the end of December 2017. I haven’t had a period since May 2018. Went to Obgyn in June and they found 1 cyst on my left ovary. I was in such shock because I never “knowingly” had one before. They told me cysts are common with people my age (24) and that it would most likely go away on my own. And that i could still get pregnant because it looked like I was in my fertile window.

Fast forward to two weeks ago (August 14th). Still no period so I made an appointment with doctor. Took blood work and got the results back in a week. They said everything was normal except my testosterone level. Which was extremely high. Now they want me to see an endocrinologist for further testing. I am extremely anxious.

My questions are:

Is this what others experience with PCOS?

Has anyone ever had something like this happen to them?

If so how long did it take you trying to conceive?

Thank you in advance!
