High dose Letrozole/HCG shot/HSG test

[kh10514]

I am 30 and have been ttc for 6 months. We think the Letrozole my Dr. prescribed made me ovulate because of the OPK, but we aren't absolutely certain. My Dr. increased the dose to 7.5mg/day, and is going to have me come in for an HCG shot when the time is right. Has anyone else done this? He also wants me to do the HSG test to see if my fallopian tubes are blocked. Anyone else gone down this road? I feel like maybe we are getting out of hand with the meds and tests.
