Why do I keep vomiting!?

2 days ago, I started feeling super unwell and started vomiting every hour through the night. The next morning there was no more vomiting but I still felt off. All was fine and last night I decided to have some cheese with a meal and this morning my stomach was crampy, I felt sick and I had literal bubbles popping in my stomach. I thought I needed the toilet so I went and have been pretty okay until now. It's 3.30am, I'm on the floor in the bathroom feeling like I'm going to throw up, stomach so bloated and hard and bubbles popping that I can actually feel on the outside pop. What is going on? Was it the cheese? Or a bug? What can I do, I feel so ill 😔
