My ultrasound. So tensed

reggie.❤️lost a baby @ 6.5 weeks & 6.1 week. ttc

So I went for my first ultrasound at 6.4 weeks Nd the doc found the gestation sac and fetal pole but no heartbeat and told me to come next week whi h happens to be tomorrow.. I am super tensed but relieved as it would soon be over.. Please tell me has anyone had success stories of finding baby heartbeat this late?
