I had sex on both the 21st and 26th. On the 6th and 7th I had extremely light spotting (bright red and stringy in my CM). It lasted about a day and a half. I am normally irregular but when I was expecting my period it never came. At 2 days late I tested and it was negative, at 7 days late I tested and it was negative same with 8 days late. I am currently 10 days late with no sign of my period. I've noticed myself peeing a lot more not consistently but more than normal and my appetite is through the roof. Should I just keep testing or what?
