http://mesdamesplusbabies.blogspot.com has details of my estrogen levels in the October archive. They were very very low to start with, and then started doubling when dosage was upped, but they were really a whole lot lower than anyone else's estrogen levels that I found. We also had to do an extra few days of stims due to the slower start. Nontheless, I got 33 eggs, 25 fertilized, and 14 blasts out of the cycle, of which 6 were chromosomally normal by CGH. I think the only effect the lower estrogen levels had was to enable me not to have many side effects during stims and then to NOT have a more major case of OHSS despite the unexpectedly large number of eggs retrieved. So what I'm saying is, don't freak out about it according to what you read on google. I did, and it was totally unnecessary.
I agree with Guinevere -- I hate getting news that my body isn't responding as it should. But this is just the first test which means they can (and it sounds like are) adjust your meds to help you get there. And as someone how had wicked OHSS, having your E2 rise slowly may not be a bad thing. Hang in there!
Stay away from Doctor Google...it will bring you nothing but panic and confusion. And nurses at the RE clinics shouldn't say anything to patients, ever. They check your E2 levels to make sure they are increasing gradually and to make sure you aren't over stimming. It is far better to have low levels that gently increase than to have numbers that shoot up like a rocket, take it from me...because then they have to cut back your meds and your eggs don't mature. Everyone has their stimulation medication gradually increase until right before retrieval, so that is normal.
Thanks so much for your comments. They made me feel much better until my appointment this morning. Sigh...
