TTC with pcos and blocked left tube

My odds are stacked against me, but my ob just prescribed me Clomid to help with ovulation. We are hoping this will get me to ovulate on both sides so I will have a better chance. Just wondering if anyone else has gone through this and had success. She is wanting me to take the clomid days 5-9. If clomid does not work then we will switch to femara, and if that doesn’t work she suggested doing surgery to unblock my left tube.
