I am currently 13 days late for my period. the last day i have experienced light pink colored discharge only when i wipe. no other symptoms. pregnant?

Maybe: One can do a home urine test if worried. A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after starting a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test.
