Early pregnancy

Samantha

Does just a couple days make a difference. Went in for an ultrasound at 6w2d approximately. They have me coming back tomorrow I think for an ultrasound but I’m wondering if 4 days really makes a difference? I’ve had two week ultrasounds and I’ve had 7+ week ultrasounds but never right in this critical time waiting for the heartbeat. I’m so nervous and afraid I’ll go and they will tell me that there isn’t one.
