Running off while pregnant

My mum walked into the room and i could see the anger all over her face. Before I could say a word I felt a heavy landing on my face and thereafter a deep roaming noise. she slapped my face so hard that I couldn't hear a word.
my dad came in to hold her. I was shaking with tears rolling down my eyes, all I kept saying was.'Am sorry mum'. she dragged my arm and kept yelling at me screaming at the top of her voice, she was now weeping.
I felt guilt. was all this my fault or was it my friends. I will say it was my fault because I was the one who allowed him get into me. I was so stupid to have brought shame upon my self and now my family is disappointed in me.
