Gemz, I felt the same way. My first visit to a Dr to get my pregnancy confirmed was a nightmare as all he kept saying to me was that I shouldn't get my hopes up or get too attached (he backtracked when I started to cry), as miscarriage can happen. This made me very anxious until one morning I saw my regular Dr as I was in a right state and he said to me that yes miscarriage happens sadly and about 10% do end in miscarriage but why am I concentrating on that percentage when the majority do end in a baby. That helped me to put it into perspective, sadly miscarriage is somthing that does happen, I wish there was no such thing but like Sarah and Sami have said worrying about it won't help, and you won't enjoy your pregnancy. Take it easy and think good thoughts xx
