This probably sounds crazy but pls let me know if you’ve experienced this and what it was!

I was laying down and my back and throat area just randomly like tightened up, almost like contractions but in my upper back and throat not my stomach. It only last for a second, and stops but depending on how i’m laying or sitting it will continue.

when i’m propped up with pillows it does it, but when i lay flat on my back or sit on the floor with my posture perfect it doesn’t continue. Baby is moving as normal and no pains in my belly. Should i be concerned or call my doctor? I have an appointment next week so i will definitely address it then i just wanna make sure it’s nothing out of the ordinary
