Doctor evaluation: It is odd to have had your Estrogen levels checked especially on day 3 and day 6 as not much information is obtained by checking this. A day 3 FSH level or a day 21 Progesterone level are more typically done. This information would be helpful in evaluating your fertility. Your doctor may have had a particular reason for doing them so it is important to contact them for interpretation.
