So I'm only 13 turning 14 in December and I've had my period for almost 2 years now and it's very irregular when I first gotten it in October of 2015 things seemed normal up until may and April when I skipped it completely...now that July-august it been happening every 2 to 3 weeks and would last for 6-10 days ...but it hasn't been a heavy flow .now to today...it seems like it went to how it was when I first gotten it back in October but it's really heavy *sorry about the pic* and it's only been 3 hours since I've changed ...Is this normal
