Baby movements

I am 31 weeks and 3 days today. Yesterday I tripped over my own feet and whacked my belly into the door handle while trying to get some laundry done. It actually hurt and left a mark but it faded after a bit. Today it is still tender, but I was absolutely terrified that I hurt my baby 😞 I called my doctor just in case and he said I shouldn’t worry about anything unless I notice decreased movements or bleeding and continued intense pain and contractions. I felt a little better about it since after about 20 minutes or so baby started kicking a lot again like nothing ever happened. But today I am just nervous again. She’s still kicking, and before I could get her to kick immediately whenever I want by just rubbing my belly, but now she won’t kick me right away or it is very delayed. My tender first time mom heart is worried about it if that counts as decreased movement and I need some reassurance that my baby girl is ok. Has anyone experienced this? Thank you in advance ❤️
