It\'s ON!

Today was a good day and I PRAY the goodness keeps on a going for the next month!  U/S showed no cysts and then they did E2 bloodwork.  I asked the IVF nurse what the E2 was and she said it checks my estrogen levels.  They want the E2 to show my levels are below 100 b/4 I can start stims.  She said if they were over 100, it was likely I was developing or could develop a cysts.  Pretty much as soon as I walked in the door from Little Rock, the clinic called and said my E2 was 37 and I could start stims so YIIIIIPPPPPEEEE!  I'm still a little confused about the E2 stuff.  Please feel free to educate me because once I start the stims on Sat, I go in on Tue for b/w only (no u/s) to do another E2, right?  And this time it should be much higher, right? Oh, I know I can post this on the fertility board but I'm too lazy tonight so I'm just gonna ask any that wish to respond:  How many days did you take stims?  My med include 9 days worth and the IVF nurse said I could take anywhere from 7-10 days worth depending on my response.  I know everyone is different....but I'm just curious to know.
