Family Planning Plus

You should have a period within 1 to 3 weeks after taking emergency contraceptives. This period may be lighter, heavier or spottier than usual. You may or may not have cramping with this bleed. The bleeding is most likely due to the Plan B; that your period started on the day of your argument is probably coincidental.

Keep in mind, that your periods may take a few months to return on a normal monthly schedule, especially since you just had a baby and recently took Plan B.

If you are not planning another pregnancy right away, consider using a reliable, long term method of birth control. You have a variety of options: abstinence, condoms, birth control pills, patch, the vaginal ring or the DepoProvera injection.
