Hello I am going through a lot at the moment My boyfriends daughter is really starting to draw a lot of attention to me and my boyfriend we are fighting and yelling at each other I am the one who bathed her and all that not sure what to do

I have really irregular periods, I was on birth control for seven years got off of it now wanting a child not sure if it’s my hormones going crazy but I am extremely exhausted all the time and irritable. I have taken tests and they come out negative what does this mean

Thank you
