Blood

I keep pooping blood? I have no cramps or anything but I was getting sharp pains in my intestines for a bit. I am 11 weeks and this is the first time I’ve had anything remotely blood or anything wrong. Overall pretty healthy. I am a little concerned I had some pork last night and after eating I was feeling a little crampy in my stomach (not uterus) and I dont know if it was bad or what? If that could cause this? I’ve also been dizzy as well and now I’m also feeling dehydrated. No other signs of issues besides the blood and dizzy. I do get dizzy a lot but it’s been about a week or two and I think im dizzy from my tummy. I dont have the means to see a doctor urgently atm. Could this be separate from my pregnancy? And just Nelly issues?
