My period was two days late so i started bleeding on the 15th and on the 17th it stopped any suggestions?

Do a Pregnancy Test: Whenever a period is not normal, it is wise to do a pregnancy test. If it is positive, please see a doctor. Specially important, if you are having unprotected sex. Sometimes, periods will change if you have had weight change or stress in your life. However, it is best not to miss a pregnancy. Good Luck!

Check pregnancy: Check a pregnancy test. Sometimes your period can start and stop suddenly and be shorter if you are pregnant. Or if you've started a new form of hormonal birth control recently this can cause you to have irregular or difficult to predict periods for a few months while your body adjusts to the hormone(s). Or it might just be a fluke and there could be nothing to worry about.
