Someone explain what is happening??

I've started having really bad back pains and feeling like I'm getting stabbed in the lower back. I also have side pains or bloating. Almost feels like blockage or something? When I push my stomach it hurts those sides. I'm also very tired and just out of it lately. It also hurt my stomach to carry a 2 liter soda on my side.  I'm not trying to get my hopes up, i ovulated 4 days ago (I think, lol). My last period was June 1-5th. It also hurts my butt area when I sit down. I'm so confused 😣
