Katiepetal, I was worried just like you when I first found out! I can't tell you it won't happen, but in the great majority of pregnancies, the chance miscarriage is very low. Try not to think about it, relax as much as you can, and treat yourself regularly to keep good vibes flowing!
Congratulations!!
You never know with the miscarriage deal, unfortunately. My first pregnancy ended in one, but many, many women are just fine. Just do what you can to stay healthy & hope for the best! :) Sorry if it's not the most uplifting msg, or msg you're looking for, but try not to worry. :) I'm sure things will be fine! :)
