Period 7days late, had a light watery red discharge after I wiped myself. I haven't had any more, just happened once. Urine pregnancy test neg. No cramps?

Vaginal discharge. Your vaginal discharge may be a sign of infection, i would recommend testing with your provider. Now with regards to your delayed period, i would recommend that you repeat a pregnancy test next week to confirm that is is still negative. And if your period is delayed for over one month, i would recommend that you see your provider also.
