Yes, try to stay positive. Assume everything is and will be fine. It's totally normal to fear the worst, but I think that's just a sign that you care so deeply for your baby.
You don't want to be so afraid that you over react to the smallest pain or discomfort. Pregnancy isn't fun, but you'll be fine. Pray for your baby. Think positively. Eat healthful foods. Take your vitamins. You're going to be an awesome mommy.
Everything will be fine that's exactly how I felt everyone around had a miscarriage before and after I found out that I was pregnant so I was freaked out just stay positive and eat healthy! :) good luck
