2nd rainbow

I just found out I'm about 5wk with our 2nd rainbow baby. I am very excited but scary at the same time. I have two miscarriage before my 1st rainbow boy baby and one miscarriage before this rainbow baby. Part of me want to tell my husband right away but the other part want to surprise him. I have plan a surprise dinner in two week to tell him.m. Praying and wishing for a safe and healthy pregnancy!
