Pregnant after m/c

Yesterday morning I tested positive on my pregnancy test. How do you moms not stir yourself crazy worrying about miscarrying or having another chemical? I’m terrified. Every lil cramp or back pain sends me into a panic. I don’t know how to cope with being pregnant again. The husband and I are both excited but I’m extremely worried I’ll miscarry again. It sent to a dark place and idk if I’d be ok if I lost another. How do you keep yourself from the worry and symptom spotting a m/c? I swear I’m going crazy over here😥
