OBGYN Fertility Recommendations

My husband and I were very lucky to have an OB that was willing to do monitored cycles with prescribed Letrozole and trigger shots. That OB just retired and we are now trying to conceive our second child. Does anyone know of an OB in North Houston that will do monitored cycles with a trigger shot? I have called many OB offices near me and they all are unwilling/unable to help us. I am a teacher and cannot afford a traditional fertility clinic. Thank you for any and all advice!
