 [ Symptoms ] why am i 19 and still have not had a period   i am 19 and have never had a period pcos is very common in my family and i am wondering if that is what caused it or what my husband and i really would like to start our family and have been trying to for the last two years and nothing has happened i really need as much information as possible because i do not have insurance until june thank you [ Disease ] unfortunately you may need to wait until june it would not be possible to determine the reason why you have never had a menstrual cycle over the internet the causes are many and we do not know anything about your medical history or have any way of examining you and yes pcos can be one of the causes to consider a work up may be expensive so waiting until june would be prudent
