Has this happened to anyone else?

I'm 14 weeks pregnant (FTM) & when I lay down for the night, my tailbone starts popping and cracking. Tonight is probably the worst it's ever been, it feels like it's ready to pop out of place. Especially when I maneuver my way out of bed to go to the bathroom I can't put all my weight down at once, I have to limp my way to the bathroom until it shifts back. 😬
