Have noticed how hard my stomach, mainly lower abdomen, has been the last few days. We are trying to concieve with baby no.2. I am 4 days late for aunt flo & very cranky plus more peeing but not really any other symptoms. Im guessing that if I am pregnant, at most it would be like 4 weeks. With my first pregnancy, I started to show at 12 weeks. My question is; could this be an early pregnancy symptom? How early did other girls notice hard stomachs? Dont wanna take a test yet as I might not get an accurate response.
