Someone help :(

So me and my husband had decided to try for a baby and we got pregnant on our first cycle. When we found out I was pregnant we were shocked and extremely happy. I have told my family and everyone is happy and I can not help but feel scared, terrified and I can't stop crying. When my family or husband asks what I'm scared of I can't even give a straight answer. I want this baby more than anything but I'm just so scared ?
