I had a ultrasound last Friday. We seen the sac and the yoc.  The nurse said that I was 5 weeks and 4 days. It was to early.

I am going back Wednesday, I will be 6 weeks and 1 day.  She said a few days makes a difference.  I am so scared.

Does these few days make a difference?  Please help me.

Oh yes that is too early to see a heartbeat! I'm sure when you go back it will be fluttering away!
