weird feeling in cervix

Hey ladies, I'm only 10 weeks and I just started feeling this weird feeling in my cervix, I have no clue what it could be. I've had random pain in my cervix since the beginning, it comes and goes but I was told it's okay. But just now I had a, thumping feeling? I guess that's how to describe it? It wasn't painful, it was just weird. It was rhythmic and lasted for a few seconds then stopped, then happened agan. I'm worried, does anyone know what this could be? 😳
