HSG Experience

My hubby and I have been TTC for 22 months without success...Doctors feels that I have PCOS and I've been taking meds for insulin and thyroid. My hubs has been tested and all looks good on his side (Yippee!).
This past week I had an HSG done and everything looked good. I've read (and been told by my OB/GYN) that this can be therapeutic and increase the chances of conception. Does anyone have any experience with this? Also, I've become so used to NOT getting bfp's that I'm a little nervous to even think that we might might might get pregnant...anyone felt this way?
