Measuring 8 weeks & 172 bpm

Hannah
I thought I was 9 weeks but baby is measuring smaller at 8 weeks. Strong heartbeat at 172 bpm. Had our first ultrasound yesterday & the tech ruined the whole experience for us. She was mad that a nurse told me I could request an abdominal scan instead of the transvaginal ultrasound. We've tried for 3 years so I'm not taking any chances. We were in the ultrasound room less than 5 minutes. She didn't let us hear the heartbeat longer than 2 seconds. Didn't even speak to us unless she was asking us to leave. Thankfully my doctor said I would never have to see her again. Now that we've heard the heartbeat I know the chance of miscarriage drops. I'm just so scared of losing our little one!
