Went to my ob/gyn to get labs drawn to check my hormone levels.

I got my labs drawn on the 3rd day of my period, so I was just in the beginning of the follicular phase. The result of my estradiol levels was 40.3.

Can anyone better help explain what this means? My nurse sucked at explaining it and made it seem like my levels were low so she said she’s going to refer me to a reproductive fertility specialist. However I’m trying to figure out what a normal range is & the internet is just confusing me more.
