Worried about fetal movement

I’ve been feeling babe move consistently and relatively strong since 18 weeks. By 19 weeks my husband could feel him, and I could even get it on video a few times when I was laying still. The movements only got stronger and more regular. I’m 22 weeks now, and I haven’t felt really any “that was definitely baby” movements since Friday evening. I know I shouldn’t expect consistent movement yet, but at what point do I contact my doctor? The fact that they were so strong and consistent before has me worried.
