Am 28 day cycle. on the 19 aug went on my periods for 5days 3 being normal and 2looking like am ending my cycle. previous week on the 9th i took morning afters. does it affect my up coming ovulation? or right after my periods i ovulated? or not yet.

For rare emergencies: Taking a morning-after pill (such as Plan B) can alter the timing of the current menstrual cycle and the upcoming cycle. Menstrual bleeding or spotting should be back to normal, after 3-5 weeks or so. One should check a urine pregnancy 3 weeks after taking the emergency contraception pill, to make sure there is no pregnancy. Home urine pregnancy tests are very accurate by 3 weeks.
