Going to doctor on the 20th?

Just wondering if this is alright to ask? 🙈 I’m 18, about to be 19, so I’m not sure what their reactions will be.. I had my first miscarriage when I was 15, and started TTC at 17 when I finished high school. I do have thyroid problems but the past 2 months I’ve been getting positive OPKs (which I had never got before) ((I didn’t do OPK testing at 15 obviously but after 17 I had never got a positive one)).

My friend just got diagnosed with PCOS as well at the same doctor and she’s a few weeks younger than me so I don’t think they’ll mind me being this young & my questions but I am really anxious so any advice would help a lot.
