i have an abnormal period. i have it between 18 and 22 days apart instead of the 20 day cycle or whatever its supposed to be. therefore, it comes twice a month. i am not sure what is the cause of this or if its abnormal or what... but yeah. also, i get a thick white discharge that makes my panties wet. i can notice it in my panties when i am just sitting in class or whatever. its not like i dont notice it until i go to the restroom or anything. it's a lot. i dont know what causes this. can anyone help me please?

i dont know if this has anything to do with either, but i am only 17 years old, not on birth control but i do have protected sex quiet often but not all the time. around once or twice a week...
