Am i crazy?

Jennifer
After having a miscarriage in September we finally got our BFP on 1/13 and we are more than excited! Tomorrow I'll be exactly 5 weeks, and even though I know I'm very much pregnant (had two blood tests first hcg at 99 and second was 770), it just doesn't feel real. Am I crazy to keep testing on cheap tests just so I know I'm still pregnant? I know it sounds ridiculous but I'm honestly scared that I'm going to just start bleeding out of nowhere. On top of that, the only symptoms I have are sore nipples and constipation with a little gas. I don't feel pregnant....Even though I am. Am I crazy?
