Ultrasound and heartbeat

Ashley

I am 9 weeks tomorrow, I had an ultrasound when I was 7weeks and 5 days and they told me they dont hear the heartbeat til about another few weeks. My next appt isn’t til 5/29. I talked to a friend who goes to the same DR and she said that she is 7 weeks and 5 days and they listened to her baby’s heart beat. I’m worried now.
