Fertility appointment coming soon!

So we’ve been trying to convince since our miscarriage 2 1/2 years ago (2nd miscarriage for me) and nothing.. I have an appointment may 13 to talk about my fertility and trying to have a baby. What are my chances of getting Clomid? I hear quite a few people are successful when they get that, and it’s really want I wanna try. The last time I went to the doctor (aug 2017) they told me I was boarderline pcos and put me on metformin and something else. But it didn’t work for me to get pregnant.. the only thing I want in the world is to be a mom.
