High HCG

Christiana • My name is Christiana. Have a beautiful little girl and an amazing man. Here for guidance and to help others if I can😊
According to my doc my levels are 24,211 and they feel I'm 6 weeks, on this app I'm only 5weeks 5days. They say this is high, but when they did an ultrasound they said they only saw a gestational sac and yolk sac. But since my levels are so high there is a possibility of more than one. 
When did you find out you were having twins?
