I just got my first period and when I go to the bathroom a drop of blood falls in is something wrong?

Menses. When you first begin your period, you may have irregular cycles with varying amounts of flow. Sometimes your period may come every month, sometimes every 2-3 months, sometimes 2-3 weeks with spotting in between. This is normal within the first year or so as your hormones are adjusting themselves. You should see a doctor if you are still experiencing irregular periods >1 year.
