Scared and worried help!!!

Alicia
Went to the clinic today and they told me I was a month and 2 weeks pregnant when she put her fingers in me to check she said she could feel the sack but when they did the alter sounds they couldn't find the baby and another red flag is I have a rare blood type Rh negative which isn't good if I'm conceiving a child . They also said that sense they can't see the baby because it's either in my filopean tube which then if the baby is in there then I need surgery to take the child out but if the lady said she could feel the sack then doesn't that mean it hasn't drop yet ? If anyone knows anything and also has the same blood type give feedback to me or even if u don't have the same blood type but been through the similar situation please respond and give me feedback
