37 weeks and lots of movement today 😐

Anyone else hit 37 weeks and had a day where your baby moved a lot for a few hours? I was a host at my job at outback today and it was stressful being the only host on and super busy. Walking around a lot also. I ate honey nut cherriohs at 9am and then ate a burger, onion rings, a scoop of chocolate ice cream and a root bear at 5. And he was moving a lot from 3-7:30ish. (Currently calmed down now) but I have had on and off back pains, no bleeding, some extra discharge, and some diahrrea today, and had some yesterday. Just curious if I should be freaking out or if things are in my head. I emailed my doctor but wanted some mom opinions.
