High HCG

St

Did anyone else have high HCG levels in their pregnancy after a MC? I had my 2nd MC January 27th and I am now supposed to be 5 wks and 3 days pregnant but my HCG lv that was taken today was 14,960 and they expected me to be 3,000-5,000. They think I am further along now and I have an ultrasound tomorrow. Anyone else have high hcg or is my time line way off? The first day of my last period was March 4th, which would put me at 5 wks 3 days.
