I took a take action pill on the 16th of last month. i was suppose to get my period on the 7th of this month, but never got it. all preg test were neg?

From the pill: Emergency contraception can cause your period to be late. As long as the pregnancy test is negative, pregnancy is very unlikely. I would just wait for your period.

Agree w Dr. Solberg: The Take Action pill may have caused this. Potential side effects w emergency contraception include menstrual flow changes (spotting, bleeding, early or late period).
