Feb 2018 last year I had a miscarriage at 9 weeks baby stopped growing at 7 weeks. No known reason. I had trouble getting pregnant . I found out I’m pregnant which was a surprise to me . I went for my first apt and they want me to come back when I’m 9 weeks for my first ultrasound. I’m scared the same thing will happen again as last time. I’m 5 weeks. What should I do ?
