Too afraid to announce our Rainbow baby!

Lo

We've had 2 early losses (at 9 weeks) and now are currently expecting our Rainbow! We saw him at our 12w 2d appt. and all is good. All bloodwork came back normal as well! How do you get over the fear of something bad happening?? I'm afraid to tell anyone besides a few close friends and immediate family! Now that we've made it out of the first trimester, I am consumed with fears of incompetent cervix and stillbirth!! HELP! I want to enjoy and attach to this baby but I don't know how to let go of the fear! Any other ladies out there that can relate? Advice?
