6weeks 1day

Just found out I’m 2 weeks behind what I should be according to my last AF. Had an ultrasound today and the heartbeat was 103 the first thing the midwife said... you could have a miscarriage or the heart rate will go up we will check in a week. I’ve read online that that is a normal heart rate at this gestational age so I’m curious to hear if any other mothers have gone through this and what the outcome was. I’ve been crying all day and I just need some help and hear other stories.
