I have a stomach bug I’m pretty sure, I’ve thrown up three times and it happens every 2 hours. First at 2 am, then at 4 am and currently at 6 am. However, I’ve been throwing up brown vomit. I can’t remember if it looks like coffee grounds but I had a small black speck on my hand because I tried to stop it from coming out but failed horribly. I saw all my food in chucks and it was super liquidiy to where the vomit sat at the bottom and chunks sat at the top and were very much known. I haven’t throw up in a while so I’m not sure if vomit is supposed to be that liquidy but please help me. What does brown vomit mean? Do I have something more serious other than a stomach bug?

My symptoms plus I feel as if I’m having hot flashes when I feel nauseous which I don’t know if that’s totally normal either. Thank you for your help!
