11 weeks pregnant and TERRIFIED!!!!

Colleen
I've had 2 MC (very early on) this year and am now 11 weeks pregnant. I've had vaginal ultrasounds at 7 and 9 weeks and everything was ok. Waiting for my next ultrasound in another week (It will be 12 weeks then) and we want to tell our family this weekend at a party that we are pregnant but I am just so scared and nervous that I will miscarry again and then have to tell everyone around Christmas that we lost the baby.  I feel like I should call my doctor to get some advice or maybe get a quick scan to put my mind at ease. Need some encouragment and advice ladies.
