Welcome to HCM.
The information provided by you is not at all sufficient. When was your last period, what day of your cycle was the endometrial thickness 9.2 mms., what is the size of the dominant follicle in the ovary, semen analysis
report of your husband etc. All these factors having bearing on your possibility of conceiving. Endometrium alone is not the factor deciding possibility of becoming pregnant.
Endometrium between 6 mms. to 12 mms. is adequate for conceiving, provided it has increased in thickness during the cycle and has not remained constant in thickness, along with triple line sign on ultrasound
examination, which states that the endometrial thickening is favourable.
Wish you all the best.
