Hi Erin - I completely understand your fears!!! I don't want to fuel them but you are correct in feeling like E2 is important. Because it is! If it weren't important...then women who use DE (and don't have a corpus luteum) wouldn't be supplemented with it.
Estrogens are important in pregnancy. In these early weeks your E2 is helping to support the early bean and the lining. (think about why we get our period...because we have a crash in E2 in the LP, among other things) Once the placenta takes over, the estrogen that is important is the Estriol (and why you don't need to monitor E2/estradiol at this point). In fact, this is one estrogen level you can look forward to fretting about.
Why? Because it is used in the blood screens for Downs/Trisomies.
You have a long medical history and I'm sure you've come to see examples of where doctors and medical institutions just don't know everything. But your gut does.
There was a time when pre-term labor wasn't understood at all, until it was discovered that in many women the reason was due to progesterone insufficiency. Hence the use of 17 hydroxyprogesterone shots to prevent pre-term labor for women at risk.
There was a time when premature babies didn't stand a chance to live. Until a doctor (she recently passed away
)discovered that it was due to lack of lung maturity and surfactant.
There was a time when babies were purposely put to sleep on their bellies to prevent them choking on their spit-up....and then it was discovered that this was a risk factor for SIDS and the "back to sleep" mantra was born (no pun intended!).
E2 is important right now. And I personally do see value in monitoring it. Because if God forbid something does go wrong, you can use that information in the future.
Best of luck to you!!
And btw - I know some may think C.ooper is overkill with their monitoring and putting too much stock in P4/E2 . So if it helps to know what a "closer to center" clinic does...do a shout out to Jaime. Ask her if her clinic thought E2 was important.
P.S. - I'm guessing Co.oper said no on the OOT monitoring because you were never an official patient of theirs? Just did a consult?
