I have a question, what can cause me to have my period 3 times within not even 2 mouths, i got it on my wedding day july 28, and then 1wk aft nd toda?

Many things: Irregular periods are common and can occur for many reasons. If you have been usually regular, you need to consider pregnancy! medications can cause changes, as can stress. A wedding and everything surrounding that event can sometimes cause enough stress hormones to affect bleeding. Other causes can be infections, endocrine issues such as thyroid and diabetes, or even more serious things.
