Worrisome call

So I had my monitoring appointment today. Everything seemed fine. The follies are all growing well. There was one a bit bigger than the others but doc wasn't concerned. He said they would check the estrogen levels and would only call if there was a problem. Well.... He called and of course I missed it. He said that my estrogen is at 1200 which apparently is high. He wants to check me out again tomorrow. Of course there was no call back number so I wasn't able to ask what any of this means. I am nervous for tomorrow. I could use good thoughts and vibes if you can spare some.
