I went to the RE this morning (CD11) to check on how I'm responding to Clomid. Last time I took it, I started to surge on CD15. The nurse scheduled me to come back on Wednesday and mentioned possible IUI on Thursday, which is earlier than I was anticipating! She said my estrogen levels were at/over (?) 500. So of course I'm googling like crazy now... Anyone know anything about estrogen levels and what this means? I just don't want to O on my own and ruin this cycle!!
