normal? no. it would be normal to have a period once per month however many young teenagers have not established a predictable menstrual cycle. you could consider seeing a gynecologist for a consultation. some may tell you not to worry about it and some my try and regulate your period to a normal cycle by using estrogen/progesterone combinations. not all milky discharges problematic or a sign of infection. some are normal physiologic discharges just like tears from your eyes or mucous from your nose. again a gynecological consultation may be helpful to properly evaluate both concerns that you are having.
i'm a teenager i've never had sex and my period comes every other year. for example it started in 2011 for 5 days. then it came once in 2012 and once in 2013. is this normal? i also have white milky discharge.
