My period is late! It was due yesterday and I’m just getting so paranoid because I’ve had sex (shown in the green dots) but protected all times of course!! I have been getting some cramps and headaches here and there shown in the blue dots. How long should I wait before taking any tests? i also took plan b in March which I know can mess your cycle up but the last 2 have been completely regular and normal periods, could it still be messing my cycle up? I’m so scared!
