Luteal Phase Defect and Recurrent Miscarriage

I had a missed miscarriage of twins in March and just had another miscarriage this week. Both of my pregnancies never made it past six weeks. I’m concerned I have luteal phase defect as I know I ovulate consistently at day 21 of a 30 day cycle. My doctor wants me to abstain from ttc for at least two months and log my basal body temperature to establish a pattern before she will explore options for me. Has anyone else been in the same situation as me? Has anyone’s doctor skipped the temp charting and went straight to prescribing an ovulation med, for example Clomid? Thanks
