14 years old. and NO im not into any sexual stuff

well, first off all how old are you? are you sexually active? if no, den its probobly just hormones acting up. If you are under 24, remember that your hormones change until you reach the age of 24. If you are sexually active, then you sure you had protected sex, you could be pregnant. Get a home pregnancy test done. That is the best way to go.. hope this helpz..

Sometimes young girls have difficult period from first menstruation up to fully developed regular menstrual cycles. It will take some time to fully develop ur mature regular menstrual cycle. Please be also informed that in general menstrual cycles r very sensitive to stress, emotional situations, infections, medication, etc.
Just be patient. Usually by 18-20 year the menstrual cycle will be fully development, ur hormones will develop ur own (personal) cycle & ur menstrual cycle will be regular.
