First fertility appointment. Advice?

Sierra

After 3 years of actively ttc with my husband, I finally had the nerve to make an appointment and get checked out. She told me she strongly believes I have PCOS due to my irregular cycle, and scheduled blood tests and an HSG. Im so nervous about the HSG and im not the best with medical things and anxiety. She also told me that I don't need to be BBT testing because it's essentially useless information but Im not sure I agree on that part. I was most afraid she would talk non stop about my weight as I weighed 270 during this visit, but she mentioned it a couple times and said it would be a good idea to lose some weight, but wasn't rude about it. The only thing that bothered me was when she said "im telling you right now you're going to have gestational diabetes." I didn't think you could predict that based on weight alone.

Does any one have any advice or similar stories to share? Thanks for listening. I'm so anxious and hopeful.
