I'm somewhere around 5 wks preg I work for an OB/GYN and we did two hcg tests 12,500 two days later 17,300 then we did a vaginal ultrasound (I have a retroverted uterus) she saw gestational sac, but no yolk sac. she is very concerned and wants to do another hcg on monday. I am very scared i'm almost 40 and I had my first and only child 16 years ago. Has anyone experienced something similiar that could give me hope for a good outcome?
