I had sex a day before my ovulation period and took pills within 2hrs after intercourse. A week before my menstruation now only my nipple hurts.
That's too early to tell if that would be PMS or a sign of pregnancy. I'm assuming the pill was an emergency morning-after pill? If so, your period could be early or late, shorter or longer and could 'act' differently for a few months. If you do miss your period for more than 4 or 5 days do take a home pregnancy test but make sure you use your wake up pee for the most accurate results and remember to post back with results. Good luck
