Trying to be really patient... It's ultrasound day

Trying so hard to not be a Debbie downer to my husband. Today we should see heartbeat.. The last 2 appointments all I could see was baby's house, and no baby, because it was still too early. Appointment is an about an hour and a half..my husband ha been married before but with no kids.. They never got pregnant. I have been married before and I've been pregnant 3 times previously with 1 success.i had a missed miscarriage before and after my daughter. She is 10 now... Previous losses occurred around 7-9 weeks with no heartbeat
