One would have to know a lot more information to answer your question. This may be hormonal or age appropriate...see a gynecologist or even your usual family doctor can take simple blood tests to begin an assessment of your hormones. I encourage you to seek medical help as this may be a problem with a very simple solution...do not suffer discomfort if you don't need to.  Good luck !
