Just wanted to pop in and say that my HCG levels at like 6 weeks were 38,000! We were convinced it was twins, went for the scan, and nope, just one. We've had 3 scans and she's been spot on her dates, so I guess she's just a strong bubba!
Im with PumpkinZulu on this one, a scan is the only way to tell. My HGC at 6 weeks was 73 000, so you really just cant tell. I threw up from 6 weeks to 37. Good luck with the scan in March and hope all are happy and healthy. Cant wait to hear
