Any advice please?

I’m 26 weeks pregnant & 1 day. And his movements are not as strong as they were 2 days ago. He usually kicks really hard were you can feel it on the outside too, but the last 2 days he’s been kicking lightly. It’s not like he’s stopped or anything, but it’s worrying me because he’s a very active baby.

He has kicked hard during the morning time when I’m just getting up but other than that it’s just a couple of times during the day where it’s really hard kicks and the rest of the time it’s just really soft ones. Should I call my doctor or just not worry too much about it?
