My periods date was 6 december, I had unprotected intercourse on 14 december and took unwanted 72 on same day within 2 hours, I experienced bleeding for 4 days from 26 december after that it's 10 february today I haven't get my periods. I also took primrest n tablet from 5 february 2 times a day for 3 days to induce periods but it's been 3 days I had finished my primrest n tablet course and still haven't get any periods.
