I fell at 23 weeks pregnant

I’m 23 weeks tomorrow and was on a walk with my family. I tripped and fell over. Luckily it was on a field- so grassy. And I think that my knee and hand took the brunt of it, I don’t think that I knocked my bump at all. But being 23 weeks tomorrow has really scared me. I’m not bleeding, contracting or anything but I’ve definitely jarred my back. I have felt movement since the fall but have an anterior placenta so I never lots of movement.

Any advice?
