ultrasound at 6 weeks?

momma • Angel mama to my son 💗 earth mama to my daughter
I am paying $25 for an elective ultrasound to check for the heartbeat when I am 6 weeks because I just need to know that the baby is okay so i can stop worrying. I scheduled it for the day I will be exactly 6 weeks. Did anyone see the heartbeat this early or should i push it back a few days to like 6w3d? I will be disappointed if i dont see a heartbeat but im also suuuper impatient. any input/advice?
