Do you know how long your cycle normally is, Or when your next period is due? It would be safe to wait until you are late to test. You can take a test 2 weeks after the incounter, but it may give you a false negative. If it does give you a negative you should wait a week and retest.

i use to be on the pill so it was a 28day cycle. do i have to wait till this wekeend to test?
