My estradiol (E2) level in the luteal phase is 103 (tested on the 19th day from the first day of my period). My usual cycle is 32 to 33 days, and I am 28 years old. Is this reading normal? Thanks in advance.

On day 19 of a 33 day cycle, estradiol at 103 pg per mL is reasonable for the luteal phase. It suggests ovulation likely occurred. For fertility tracking, also monitor progesterone 7 days after ovulation.

Dr. Hema Suggests...

Take a Progesterone Test Test or Take a AMH Test (Anti Mullerian Hormone) Test
