Reduced movements?

I’m 38 weeks tomorrow, she’s usually very active. This morning I woke up when my husbands alarms going off because today’s my day off, and I had to go to the bathroom, then I came back to bed. And while trying to sleep I just got the feeling that something wasn’t right and I hadn’t felt her move since last night. So I drank a big glass of oj and had a piece of chocolate and layed down, and it took a while before I started to feel her move a little. So I went back to sleep and when my son woke me up I got the same feeling. So I had a piece of an apple and layed down again. She’s moving a little, not as much as she usually does. I have an appointment today at 11:50 and my husband says I’m just paranoid but I’ve been having nightmares of her being stillborn or something being wrong, and I’m just not sure what to do
