Irregular periods: Nobody has a completely predictable menstrual cycle all their lives. It is very common to have some variability from time to time. However, if you are sexually active, it is always a good idea to check a pregnancy test if your cycle seems different. Some women get spotting early in pregnancy. But, it may be that you are just having a light period this time. No worries then.
