Worried

Hi,

So this will be my second pregnancy if I am pregnant. I have been cramping mildly for almost 2 weeks (will be two weeks on the 26th). Also extra gassy, more sleepy, craving chocolate ( I useally don't eat chocolate except for period or holidays). Peeing more, headaches, and my fiancee says my boobs have gotten bigger. I'm waiting to test till 26 th (the first day glow says is my next period) but all the things are worrying me, if I'm pregnant great, if not what's wrong with me?
