Check pg test.: Check a pg test anytime your period is abnormal, in length, symptoms, or timing. Repeat in a week and if negative, and you miss another period, see your doc to find out why. Follow the instructions on the kit, and be sure it has not expired, too. Also, infections can occur, if you are at risk of pregnancy. So get checked for those if your pg test is negative. Practice safe sex!
