I don't know much but hate to see a post unanswered. I found this information about what levels are normal
The reference range estradiol in women varies by menstrual cycle and menopausal status, as follows: Before menopause, estradiol levels are widely variable throughout the menstrual cycle: Mid-follicular phase: 27-123 pg/mL. Periovulatory: 96-436 pg/mL.
I hope that is some help to you.
