Fear of losing again

Brittany
I'm am 5w6d today! I had a miscarriage in sept (lost the baby at 6w) I am constantly analyzing every twinge and cramp, checking myself everytime I'm in the bathroom, and preparing myself for the worse. I feel my fear of losing is trumping my excitement :( my OB let me come in yesterday for peace of mind. I measure to the exact day and we even detected a heartbeat❤️ I can't thank God enough, but feel like I can't shake my fear. Is anyone else in te same boat? Any advice?? I'm driving myself crazy
