Idk what to do

I feel like this baby has caused nothing but trouble. I'm so emotional I can't handle it. My fiancé and I got into a fight and I tried telling him how I felt but he didn't listen. Now I feel like I should get an abortion so I can go back to normal and he won't be so mad at me. I can't help how I feel when I'm pregnant. Idk I'm sitting in the bathroom crying cause idk what to do.
