Stomach Ulcer

So I have been having bad stomach pains and feeling really week and honestly it feels like my insides are burning and my ribs hurt and my insides are swollen. I've also had blood in my poop the past two days (not a lot) my mom says it's a stomach ulcer, I've never had one before she has. Anyways is there anything I can take to help with the pain or get rid of it? I don't have insurance to go to the doctor right now.. I was also constipated for over a week so I'm pretty sure that's why there was blood in my poop. Because it happened literally the first two days I was able to poop again.
