Endometrial biopsy has been shown to improve IVF pregnancy and live birth rates. The optimal time of performing the biopsy is yet to be established.

In this study, the investigators will compare different temporal timing of the biopsies with regards to the menstrual cycle and their affect on the success rates of the treatment.
