Hello and welcome.
I am Dr. Norm, and I look forward to helping you today.
I think that the chance of this being a viable pregnancy is very low. Even though the hcg has been increasing, the dip from 96 to 60 is probably not compatible with a viable pregnancy.
A pregnancy won't reliably be seen on vaginal ultrasound until the hcg is around 1000, so it's not too surprising that they didn't see it 2 days ago. With a viable pregnancy, a sac is usually seen by 5 weeks with a viable pregnancy, which also suggest that yours is not viable.
As long as you don't have pain, I wouldn't worry too much about an ectopic. A miscarriage
is far more likely. If you do develop pain, and nothing is seen on vaginal ultrasound, a biopsy inside the uterus
showing placental tissue would help to rule out ectopic.
The fact that the hcg is increasing means that there is viable placenta growing, but doesn't mean there is a viable fetus
. I'm sorry.
