The only real medical reason you could be unusually tired during your period is if you have anemia, which is an iron deficiency. For some women who are anemic and have a very heavy period, the first day can be a doozy. However, this group is in the minority.
Here are some of the most common reasons that periods may be irregular: 1  Youâve just started menstruating. If you only recently got your period, it can take up to a year or more for your hormones to properly regulate. 2  If youâve been under a lot of stress. Stress can really effect hormones and female cycles. 3  If you have started birth control recently.
