Upadate on my cycle

I went in for my cd 15 follicle scan today to see if my follicles grew any more, thursday i had 2 on my right at 14mm, Well it turns out they went away. Or as they say they fizzled out. I have one more on my left ovary at 15mm that they didn't see on thursday. My RE said that she wants me to come back on monday so they can look at the again! My estradiol levels went from 64 to 100 since thursday and they said thats a good sign and my progesterone is still staying low which is also good, It went from .25 to .28! Im very hopeful things will go well. The nurse was shocked that I produced 3 almost good follicles on only 50mg of clomid. They said they will take me to 100mg my next cycle.
