Brief Answer:
irregular cycles

Detailed Answer:
Hello,
If the menstrual date was 12th, and the sexual encounter was on 25th, then it was during the fertile period. Pregnancy was a definite possibility.
After taking the emergency pill, withdrawal bleeding should start with a week or two. If there was just spotting for a day, there is still a chance of pregnancy unless there is a normal bleed. Wait a till the next period and watch. If the period is missed, then wait a week and take a test. Right now, nothing else can be done. Emergency contraception can only work once.
