6 wk 4 day ultrasound.

Kimberly
Ok ladies.. so I had my first ultrasound on the 20th of last month. We thought we were around 8 weeks but they said we were 6 weeks 4 days. It's had me puzzled. I've looked at other women's ultrasounds at 6 weeks 4 days and they all look so much smaller. I swear I already see arm buds and eyes. Is it just me ????
