Diagnosed with Short Cervix today😭

My anatomy scan was today, I’m currently 19w3d, and it was beautiful. Baby was perfect, moving around amazingly and have no issues or complications. I was on cloud 9 bursting with excitement, until we had to talk with the Dr. After to go over the scan. She said my cervix is measuring at 22mm (but it’s not open) and that she will start me on progesterone suppositories so that it won’t shrink any further. I’m so nervous and scared😭 Anyone else went through this?
