Pregnancy after miscarriage

A few months ago I got pregnant for the very first time the baby stopped growing at 6 weeks. My husband and I were going to wait 3 months but I had one normal period and then found out I was pregnant again. I was 7 weeks and had a gush of blood so I thought I miscarried again I was crushed. I didn't go to the hospital cause I had a doctors appointment in two days from then. When we went in we saw a heart beat. There was a small tear on the placenta. I'm now 10 weeks and have a doctors appointment Thursday I haven't bled in 3 weeks but I'm still nervous. Has any one been through anything similar?
