Not feeling pregnant...

Hi March moms!! I'm due March 17th with my second. Super excited and happy but a little concerned. With my son I felt pregnant right away and continued to throughout my entire pregnancy. This time not so much! My boobs are a tiny bit sore and I get very mild aches in my uterus here and there. I've read that with the second pregnancy you don't feel symptoms like you did with the first, but I'm still worried. Anyone feel this way???
