Should I be worried?

So i can usually feel my baby moving a lot throughout the day especially when I lay down like on my back but i didn’t feel her at all yesterday, I thought maybe it was because I had a busy day and just didnt notice but now I just woke up at 4 am and for some reason I’m scared shitless that something is wrong because I still can’t feel her moving and I’ve taken a shower and everything is it normal for them to move less some days at this point in pregnancy? I’m 30 weeks
