appointment. Always worried!? Is it normal to feel like I might miscarry or lose one twin? I keep picturing the monitor at my next appointment with one baby or no heart beat. I am trying so hard to think positive but I had a miscarriage last time I was pregnant which was 2 years ago. I have a beautiful 4 year old girl. I found out I was pregnant and was more surprised to find out it was twins, the first thing my dr said was that one might not make it. My next visit isn't till 3 more weeks and although time usually flies for me it has been standing still! What are the chances I'll miscarry again?
