 But you know something's wrong when you're still bleeding, two weeks later, I mean you're on the phone to your doctor and if that doctor doesn't help you get another because really we, as women, we don't want to keep bleeding forever. No, we certainly don't. You can say that again. The rest of the day we stop. But so, what about when we get older? I mean it does change. So how do we know like okay it's just changing and it's fine or no, this is a problem? That's a good point because when we get older we start getting periods a little bit closer together. So it's 28 days, maybe 25, 24 and then we might miss a period or two, get a few hot flashes. But a period shouldn't get heavier, they shouldn't get longer and we should not spot in between. That's clearly abnormal and that's a good reason to call your doctor because we want to make sure there's nothing serious going on like a cancer.
