I started when I was 13 and I still am not reg. Is there something wrong?? I hate even talking to my mom about anything personal... the most I have ever had in a year was 4 to 6 months of an actual period, the rest where skipped. I might have only had three in one of those. My sis tho is all ready regular and could tell me when her next one would be (She is two years younger than I am)
