and yes, it was determined by u/s only, based on follicle sizes, and did the IUI on Day 10 (and lots of BD
). again, not sure i ovulated until day 11, though.
i've been wondering about E2 testing after day 2/3. you all keep talking about it and i'm kind of confused why i'm never tested for it? they just figured ovulation based on u/s and follicle size. i mean, i am new to this (this is my 3rd month with an RE, already on dr #2 b/c the first one was basically unfriendly to high fsh.)
i've also asked so many times about whether i need p4 supplementation, based on what i've read here, and i'm repeatedly told i don't need it.
