Does Taking Huge Amount Of Vitamin C Cause Miscarriage?

I was recently sick and took a huge amount of vitamin C to help speed up healing. I ve been bleeding really badly since then. I figured it was just my period, bit after thoughts about how this has been happening for two weeks, I relized I missed my period by three weeks, and this isn t my usual time. I looked into it and found that vitamin C can cause miscarriage. This would be my second-third month. I am also cramping very badly. Is this a possibility and if so what do I do. I had no idea I could have been pregnant. Looking back on it, the nausea and fatigue makes sense. Please help.
