Hi! I'm 16, and have had my period since I was 9 years old. I am very irregular, and always have been. A few months ago, I bled a whole month and then missed two months entirely. I haven't had my period since the first week of April and it is now June 18th. My mother had endo. And it has run through a lot of women in my family. Most of the time, when I do get my period, I have cramps that leave me bawling on the floor. HELP PLEASE!!
