@taminaminam it looks like that one is a urine test
@madasrabbits @taminaminam I am not an endo, but they say it measures E3G, which according to FDA "estrone-3-glucuronide (E3G)" "E3G is produced when estrogen breaks down in your body. It accumulates in your urine around the time of ovulation and causes your cervical mucus to become thin and slippery".
So I'd conduct some additional research to check if E3G levels correlate with E2 levels for transfems.
@IngaLovinde @madasrabbits thanks, yeah that's what I was worried about
