No 💗 During Gender Reveal Ultrasound

I am 13 weeks 6 days. January 13 I'll be 14 weeks 5 days; we are going to Prenatal Peak to find out if it is a boy or girl. I know this is silly but I'm having nightmares about it and just want someone to either tell me I'm fine or this is possible. I keep dreaming that when we get to the appointment we won't find a heartbeat. I have had no physical symptoms of something being wrong and the heartbeat has been strong during our two ultrasounds. Ease my minds, Mamas! UPDATE: We do have a doppler and we have only been able to find the heartbeat at home once, but the dr never has an issue.
