frustrated

may.29 we found out we are expecting. I had light spotting on June 1st do I went to the E.R. They ran test and my hormones was at 5177. They also did an ultrasound and my pregnancy is in the uterus and they see a yolk sac. I went back on June 3 to check my hormones again and it only raised a little to 6708. Doctors are really worried and says that the hormones are supposed to double. They said I may have a miscarriage. I am so depressed. Today I went back to check my hormones and it went up to 9758, it went up a lot but didn't double. Have anyone else have hormone problems but still had a healthy baby? Or did in fact miscarry?
