Okay so AF was due the 13th and have had nothing some minor minor cramping peeing a lot back ache well today I went to the bathroom and when I wiped it was pink well the next time I went I wiped a little bit of brown? Nothing on my underpants nothing like that and the only test I took last week a white lined appeared as soon as the test began ? Am I about to start or should I be worried I am freaking out...
