stopped rolling after her shots

So this is in no means an anti vax post because I am totally and completely pro vaccination. I took my 4 month old to her well visit this past Monday and she got her shots. She did great, didn't even cry. She has seemed fine other than the fact that she has completely stopped rolling over. Idk if this is due to the fact that maybe her little legs hurt or she doesn't feel good but she hasn't rolled over once since the shots and she used to roll both ways multiple times a day. Has this happened to any of your kids? Should I be concerned? I put in a call with her pediatrician and I'm waiting for her to get back to me. I'm just such a terrible worrier and I'm terrified its a symptom and something jot being quite right😕 I would appreciate any feed back you momma's have!
