Non supportive mother

Well I just found out I'm 5 weeks pregnant after I suffered 2 miscarriages 1 back in October. So hubby and I had decided not to tell anyone from past experience. In the first miscarriage my mother pretty much said it was invalid of me to be in mourning or sad because it wasn't a real child. My "best friend" at the time told me my husband would leave me if I didnt give him a child soon and my aunt spread a rumor that I was infertile and couldnt have children. I was deeply hurt by the people I thought were supposed to be there for me. well I was having an anxiety meltdown today because I'm so scared it will happen this time again. so I decided to call my mother to have someone to talk to and help me calm down and the first thing she says after I tell her is "why didnt you take care of yourself to not get pregnant?" I hung up on her right away I was in tears and that first comment made me feel worse like if it happened again it would be all on me. All I wanted was a "calm down, everything will be okay, I am here for you" but no. Did I overreact? Is she in the wrong? I am hurt I feel alone and I would like some support.
