HCG Shot

Jessica
My doctor put me on clomid at 100mgQ for five days. I went in for an ultrasound and my ovaries some activity in my right but in my left there was absolutely nothing going on. He upped my second round of clomid to 150mg for five days. I went back for an ultrasound and there were two "contenders." One in each ovary. He prescribed a HCG shot to be given today actually and I was just wondering if anyone has had any luck with this? Thanks!
