Sadly, it looks like the Clomid this month was too much for my body. I have one follicle that is ready to ovulate, but my lining is only 5 mm this time (as opposed to 7.5 mm last month, which was already thin). We are going to try estrogen still, but it is likely that I will ovulate on my own very soon and the lining probably won't thicken after I ovulate. The doctor said he has only seen a few pregnancies acheived with a lining that thin in his 40 or so years as an RE... So the good news is that I shouldn't be too disappointed at the end of this month, since I'm pretty sure I won't be pregnant. The other good news is that I won't have any more Clomid headaches, since I won't be taking Clomid any more! Woohoo!
Thanks for your prayers. We're most likely going to take a few months off to let my body rest and recuperate, so we probably won't have any updates for a while. Unless I actually start blogging again. :)
