I'm an 18 year old female and my periods have been somewhat irregular last month, and right now. Last month for like a week I was bleeding very lightly then the next week it was like my normal period. Well, this month it's been really weird. I was bleeding lightly for about a week again and I'm still bleed pretty heavily, like it's not about to let up any time soon. And it's very different from my normal period because it's usually pretty heavy for the first few days and I NEVER bleed at night. But this time it's constant... I don't know what is going on. I've bleeding like this for about a week today but like I said it doesn't seem to be getting any lighter or like it's going to stop anytime soon..

Are you sexually active?
On any medications, anything?
We could ask questions all day and it wouldn't be enough.
Give it another month unless you don't stop bleeding. There are various conditions you can read about - PCOS, fibroids, endometriosis, for starters.
Most are accompanied by discomfort all the way to real pain, but not necessarily.
It could be NOTHING too! We all have irregular months.
If I had a nickel for every girl or woman who says 'I never had this before' I'd be rich.
