... an hour ago and it showed up negative. However I still feel strange, Iv been having loads of pregnancy signs although I know some of these are also period signs. On Saturday I had bad period cramps like usual but have not come on my period, Iv also got really painful boobs and have a burning sensation in them too which I have never had before. I just don't feel like my normal self and I usually know my period. Do I take another test in a couple days or is it 100% accurate! Is there also a best time to test like at night?
