Hello Dr. Sher,

I am experiencing my 4th biochemical pregnancy in less than 2 years. I am 45 years old with 8 previous live births. My youngest son turned 2 years old in January. I recently acquired Day 3 labs and my AMH is .71 though I obviously have had no issues with spontaneous pregnancy. I have not evaluated my progesterone on Day 21 but I plan to do so the next cycle. Do you have recommendations or have you seen cases that are similar? I have regular 31 day cycles with normal luteal phases. I have normal BMI. I am not on any medications.

Thank you,
