Blood gush at 7 weeks... anyone else?

Emily

I was at our family doctor today for a we'll check for my 3 yr old. I was filling out paperwork and all of a sudden a bunch of blood gushed out. Went to the bathroom and more bright red blood came out. Our Dr fit me in as well. We did an ultrasound and saw a healthy baby with a heartbeat of 160. He/she had doubled in size from last week. Has anyone else had this happen and had positive results???
