I am waiting until the morning to take a HPT, but today on my 1st missed period day, I have had light cramps on and off. I have been more light headed lately and I have to urinate more frequently. If I am prego is the light cramping normal? I always start on time, even around the same time on my starting day. Oh and I would say I have a little more gas than normal which normally helps the light cramps go away...
