Sometimes a person cycle can change for no reason at all. So if this is the first time this has occurred, I wouldn't worry about it too much. However if this irregular bleeding continues next month, then you need to see your doctor. When it comes to irregular cycles, there are several causes. Examples; stress, weight gain/loss, medication, illness, climate, cyst, or polyp of the cervix, hormonal imbalance, thyroid, infection.. just to name a few. So if this happens again, the bleeding lasts for more than 10 days. If you start to go through a pad/tampon in less than an hour, do be seen right away. Otherwise, follow up with your doctor if the irregular cycle continues beyond 10 days or if it continues to be irregular.
