For a couple of weeks now I have had serious stomach ache and nausea after eating it can take up to half an hour to start. I haven't been fully sick but acidic stuff keeps coming up my throats when I burp. I don't know whether it's related but when I wipe after I have pooped there's always a bit of blood on the toilet paper. I haven't been to the doctors yet but I'm getting worried now and would appreciate it if anyone could help. Thank you.
