Pregnancy after miscarriage

Last year I had 2 misscariages 6 months apart the first at 6 weeks and the second at 11 weeks. I'm currently just over 12 weeks pregnant and can't bring myself to go to the doctors even tho I know I should. I'm so worried that there will be something wrong and I don't think I could handle going threw that again. We havnt told anyone about the baby yet and since I'm showing a fair bit already we have been avoiding everyone. How do I overcome the worry? I want to be able to tell my family but it makes the situation so much worse when you lose a baby and have to announce it and have everyone ask if your okay and feel sorry for you.
