3 Days late negative test

Hi I’m 3 Days late have nausea day and night. I feel very sick weak and lightheaded. My lower abdomen keeps jumping and I get stabbing pain on my ovaries. I feel like I’m going to pass out and when I get up my vision goes completely black. I have three children and every time I’ve missed my period and test it’s positive. This time nothing except for all negative and pain. I know a lot of ladies are hoping to conceive that isn’t my case though I am hoping it truly is negative. I’m in a toxic relationship domestic violence and been trying to escape this hell hole. He packed his stuff and said he was leaving us but is still here making our lives miserable. I pray it is something else not because I don’t love children but because my life is hell. I don’t want to bring another child into this cruel life and I am not capable of taking its life either. It could also be a lot of stress. Im freaking out has this happen to anyone.
