Welcome to HealthcareMagic Forum. It is common to have irregular periods
after taking emergency contraception
. I hope you have taken the pill within 72 hours after the unprotected intercourse
. If you are worried please go ahead and do a pregnancy
test. You can get a pregnancy kit and do the test at home.If you are not pregnant, please do check if the same irregularity continue in your next cycles as well. If it does, please seek care from a gynecologist. Take care.
