Stay hopeful?

Meaghen • I finally got my positive test on 5/13/16, I had a confirmation appointment on the 17th. We are expecting by January 21st. I couldn't be more excited or happy.
I have PCOS, I'm taking metformin for it, and my boyfriend has a low sperm count, we have been trying for the past few months to conceive and still nothing. Should I stay hopeful? Any success stories?
