Kinda worried

So today I had to use the restroom and so I went and I went number two, I looked down and there was blood like I had peed dark red blood and so I assumed it was period starting but I didn’t pee. So I cleaned that area and there was blood but it wasn’t coming from my private area I called my mom told her she said to just lay off the spicy food. So I laid down and felt super tired later started feeling cold like I was having the chills I turned off the AC but was still cold I was nearly shaking It stopped after a couple hours and now I feel really warm and still sleepy. It didn’t hurt going to the restroom at all, during the previous week I had been feeling bloated and constipated & some what cramps & really sore breast which is why I assumed my period started but it didn’t. Should I worry? And recently I feel like I’ve got an uti infection after I pee I have the sensation to go again but nothing comes out.
