Are you 6 weeks exactly? The reason I ask is I had my first scan at 6+5, and even at that close to 7 weeks, baby was hard to find! My tech said she couldn't see the baby yet, just the ges and yolk sac, but then she finally found baby, up next to the wall of the sac. I have very regular periods and short cycles, so I was sure of my dates. I wouldn't give up hope at 6 weeks. So much growth occurs so fast! You could go back in 2 days and see baby. Hugs and prayers for an awesome outcome!!
