I am from what the doctor's say about 5 tp 6 weeks pregnant. My HCG level went from 391 to 400 then 763 then 1900 then to 1768 now at 2287. I have been bleeding for 3 weeks and have passed what looked alot like tissue and blood clots. The doctors told me that i had miscarried but now mylevel has gone back up. My cervix was also checked andwent from open to closed. An ultrasound was doen and nothing was seen except for some fluid on the outside of my uterus and was told it was too early to see anything. What could this mean? This is my first pregnancy and I am 19 years old and terrified. Any answers would greatly help.
