If E2 level is 37.6pg/mL (& not 376 as typed) hormone levels are normal. If E2 level is 376, you need to recheck it, as it can't be that high on Day 3 of menses. Regarding chances of pregnancy
, only hormone levels can't predict pregnancy. It requires normal semen analysis
, open tubes & regular menses(meaning monthly egg formation).
Wish you good health.
