I’m sick is it normal for baby to be moving less?

E

Currently I’m 29+4 I caught a cold about 5 days ago. The last like 3 it’s gotten worse with me having a bunch of mucus and my head throbbing, but baby had been fine moving a lot and being active. Today he isn’t nearly as active, but I’ve been sleeping most of the day. Is it normal for him to be less active because of this? Should I be more considered or call the doctor?
