1st OB appt tomorrow & nervous!

Laura • Pregnant with our rainbow babe :) Due Sept 17! ❤️
Hi ladies,
I have my first OB and ultrasound tomorrow and am trying to stay calm. I am super anxious and irrational thinking they won't hear the heartbeat :( I think I feel this way because I haven't had a ton of symptoms beyond fatigue and sore breasts. I am just shy of 8 weeks. Any prayers and words of wisdom are appreciated!
Thank you!
