Needing advice on telling parents

I'm 18 and my husband is in the military. We got married a little over a month ago. I've stopped taking my birth control 4 months ago because I hated the way it made me so angry. I didn't tell my mom I stopped taking it so she keeps asking me how I'm doing with my birth control and I keep avoiding the question. She keeps saying you're gonna end up pregnant and saying that I'm dumb for doing that. I found out I was pregnant yesterday. I'm almost 2 weeks late. I took 4 pregnancies tests when I was 5 days late and a week late and they came up negative but I took one last night and one this morning and they came up positive so now I'm dealing with how I'm gonna tell my mom. I'm afraid to tell her anything because she gets pissed at anything. Like when I told her I was engaged and when I was getting married.
