So I'm 11dpo today and just been for a wee and when i wiped there was blood on the tissue it was very light in colour but it was there when I wiped. Af not due till next Thursday. Could this be implantation?? Or a very early period ?? I'm only ever early by a day I'm more late sometimes never early. Since 8dpo I've had tingly nipples and really sore boobs. Xx
