I'm 16 and I got my period when I was 14, but I'm still not regular. Like sometimes I'll skip two months, and when I do get it, its always like a week or two off so I never know when Im getting it. Its also a problem because this has happend in school when it came like 2 weeks late and it went threw my jeans, luckily I noticed this before anyone else did, but is this normal and is there anything I can do about it?
