I had my estradial taken today and when the nurse called, she said it was good but not as high as last time. I can't remember what it was before and this time it was 167 this is d8. Anyone know what a "good" number is? I'm going in for US tomorrow so hopefully I'll have a good follicle for IUI but now I'm worried since it is lower than last time and obviously the last one was unsuccessful. I guess I don't really even know what it tells. I should have asked her when she called and I will tomorrow when I go in, I'm just impatient and thought some of you might be able to help. thanks.
