I'm not exactly sure how far I am into my pregnancy, but my b-hcg is at 2600 and my doctor believes I am pregnant in my abdomen. I've done 5 ultrasounds and there is no sign of pregnancy. Any suggestions?

More info. When was your lmp? Have you had any vaginal bleeding? Over what period of time were these ultrasounds done? Have there been any other HCG levels drawn? If so, what were their levels? A pregnancy in the uterus should be seen on a transvaginal scan if the level is above 1500miu. If there was bleeding and you miscarried HCG could still be up without a visible pregnancy.
