Emergency Contraception
"Plan B did what it was suppose to do. Had unprotected sex a day before  ovulation (assuming ovulating day due to my period app) by accident. 11 hours later I went to Walgreens purchased Plan B.  2 weeks later I got period only 1 day late. However 1 week after Plan B was taken I started spotting lightly until actual day of period.  So everything went great, as far as taking this on or before ovulation day."
