Plan B helps prevent pregnancy by delaying ovulation. Plan B may cause your periods to occur earlier or later than usual. Your bleeding may be lighter, heavier or spottier than usual. Since you had period like bleeding in January, it is unlikely that you are pregnant.
If you are not planning a pregnancy, you may want to consider starting a long term birth control method like the pill, Depo shot, patch, etc. Correct and consistent condom use can also be an effective method of preventing pregnancy.
Family Planning clinics offer free STD screenings. Gynecological exams and birth control are offerred at little to no cost, depending on household size & income.
