Hererotopic Pregnancy

A heterotopic is a very rare condition where I had one baby in the uterus and one in my right tube. I had emergency surgery a week where they successfully removed my right tube and unviable pregnancy. One Monday my HGC levels were 26502 and on Wednesday they were 43878. Not quite doubling but still a nice a jump. I have another ultrasound tomorrow. The one I had last week just showed an empty gestational sac but I was six weeks at the time. I’m 7 weeks now so hoping to at least see a yolk and fetal pole. Even just a yolk would be encouraging. I’m so nervous. Survival rate for the inter uterine pregnancy after a heterotopic is 67%.
