Unexplained infertility?

Brittany • Baby Mason is due on February 7th, 2017 ❤️ baby #1
My doctor says I have "unexplained infertility" and even though I get a positive ovulation test right on scheduele, she is putting me on femara for 2 cycles, and if that dosent work then I will keep taking femara and get an <a href="https://glowing.com/glow-fertility-program">IUI</a>. And if that does not work, then we are done trying because we can't afford to invitro!
