Pregnancy after a miscarriage!

I know I probably should be like super excited that I get another chance to try to have a baby with my husband but I'm not gonna lie I'm a lie but nervous! We honestly didn't wait all that long after the miscarriage to conceive again but it happen. Now I'm concerned is it to soon? Will this be a better pregnancy? Am I healthy enough? My mind is going a mile a min my husband tells me to be strong and pray and hope that our lil jelly bean grows strong and healthy!
