Sick but with what?

Sorry this is gonna be long but trying to give as much detail as I can go get an idea. So Wednesday before thanksgiving I was feeling great didn’t feel sick at all, well about 5-10 min after my daycare kids left I suddenly felt like crap with tooth pain. I was up every 45 min threw the night in pain, well I finally got to sleep more then 45 min and work up feeling sick to my stomach, sent my husband to his parents for thanksgiving and I decided to sleep more. I woke up feeling fine and went to have dinner and we went shopping, I was doing fine while shopping tell I got really hot waiting in line at the last store. We came home and I took a bath and still felt like I was gonna throw up. My bath seemed to help then I was just sitting in bed watching tv trying to sleep and I took off running to the bathroom to throw up and went to bed. Friday I was fine and Saturday I felt fine also, well today (Sunday) I woke up with top teeth pain but it was bearable well I got more and more nauseous during the day and threw up a few times but I also was sooo hungry so we went to get food and got home and I ate about 4 bites and I would have a hard time swallowing it cause I wanted to throw it back up right away and now it’s 2:30 am and I can’t fall asleep cause I feel like I’m gonna throw up. I’m also shaking and can’t figure out why. I don’t have a fever.

I’d go in but I do not have insurance at the moment. With that being said anyone have any ideas?
