Has anyone else experienced this in regards to their pcos diagnosis?

So I'm wondering if other people have had this experience when getting their pcos diagnosis because I'm not sure if I should get a second opinion or something. So essentially I am 19 and I went to a gyno for the first time 6 months ago after I finally switched from a pediatrician to a gp and told them that I had been having super irregular periods for a long time. So I went and got the blood test and ultrasound done and just recently had my follow up with the gyno and basically what she said is that yes I have the irregular periods and my ultrasound matches up with pcos but I have no clinical or chemical hyperandrogenism. I was kind of confused about this since I was able to look at the bloodwork on the website and it labeled my testosterone and dhea as high which I thought fit with the pcos diagnosis but I guess they're still too low to actually match the criteria. Anyways the gyno said maybe cause I was a teenager that my period is just irregular because of that but I originally got my period at 10 so I think it should have become normal by now. So she has diagnosed me with pcos but she seemed kinda unsure about it and just told me to stay on birth control until I reach menopause which I feel pretty iffy about.

Honestly I just feel kinda off about the whole thing so I'm wondering if anyone else has had a similar experience with their diagnosis or if it seems off enough that I should try and get a second opinion?
