Pregnant After Miscarriage

Found out last Wednesday that we are expecting again. I miscarried naturally on October 18 at 10 weeks but the baby had stopped growing at 6w5d. We have tricare (military insurance) so there won't be blood draws to check progression or development. So we won't know anything till I'm 10 weeks. That's when they see me for the first time. I'm so scared that it will happen again. Waiting is driving me crazy. I'm only 5 weeks and have another 5 more to go. Please, pray and wish us luck that this is our sticky rainbow baby.
