Kathryn

Has anyone ever had an HCG level of 8000 at 5weeks ? And also has anyone ever went to the ER and they said they seen a sac but no baby ? Ill be 6 weeks Sunday and I have an ultrasound with my OB Monday. Any advice ? I had a miscarriage in Dec of 2019 and I'm so nervous..... BTW my due date is 2.13.21 , my daughter's birthday is 2.12 ♥️ she'll be 6 .
