Estradiol levels and follicles...

Does anyone know what the estradiol level of 613 means in relation to follicles? Is that level too high for just one follicle or does that mean I have more than one releasing?

I did my 4th round of Clomid and at my ultrasound, I had 4 follicles. Labs were done and I triggered Saturday night. The sound of 3 or more babies is making me a little nervous!
