Has anyone ever missed their weekly progesterone shot during pregnancy? Was everything fine?

.

I’m 30 weeks and get a weekly progesterone shot. The nurse that did it on Saturday shoved the auto injector into my arm and then stopped holding it firm to my arm and there was a puddle of the medicine on the floor and the counter so I don’t think any of my medicine even went into my arm. I’ve been so paranoid and just wish it was next Friday already so I can get my next shot by a different nurse. I’m scared of something happening since this nurse gave me my shot wrong and I basically didn’t even get my shot since I’m pretty sure none of the medicine went in. Has anyone missed a weekly progesterone injection and everything end up okay?
