TTC & Infertility

So long story short, I'm obviously here due to the title, but also I'm a newly wed and we have been TTC for over a year and a half now with no luck. Neither of us have children or have had any pregnancies in our past. My husband hasn't been tested yet to see if he has any fertility issues. I however know that I for sure have PCOS and was first properly diagnosed with it in 2014. I am going to a new doctor one week from today and I am nervous. It's been since 2014 but I did try clomid and it was not successful, even with the highest dose given to me. I'm worried at 31 years old that my chances just keep slipping farther and farther away from me. My best friend is having her second baby tomorrow. I don't have a single friend that doesn't have kids. I know better than to obsess over this, but it's also hard not to. What should I do other than just wait for my appointment and blood work? Maybe I'm being a selfish little shit and maybe a bawl baby over this. I'm trying not to be. This is just difficult. Anyone else in my shoes?
