8 weeks 1 day first ultrasound

So I had my first ultrasound today. I saw the sac and something inside. Then the doctor turned off the lights and we saw a heartbeat! Didn't get a heartbeat number because it wasnt easy to see. The doctor also said they don't hear it this early just see it. But she ordered a vaginal ultrasound so we can see better and because I had a miscarriage in May so to ease my mind. But she said if you see the heartbeat chance of miscarriage goes down to 5 percent! Feeling hopeful!
