Okay so my period was supposed to start March 3rd but now it is 7 days late. I tried a couple pregnancy tests and they both were negative. I don’t have sore breasts but I’ve had diarrhea, cramping, fatigue, headaches, acne and a sore back. I haven’t changed my diet or anything. I have felt like I’ve had more clear discharge than usual. But I don’t know what’s up. My periods been late before but never later that a couple days.. Should I just wait a little longer and see if it comes or take another test or ask my doctor..
