They probably aren't normal yet
Yes a period can do thios If it is this heavy then try not to go to school or work when it is this heavy because it can also be very smelly.
It is different for everybody. Some do some dont. So I guess it is considered normal.
Only if they are girls! But yes they do have periods. Otherwise they could not have babies..... No matter what I'm pretty sure that girl dogs do have periods. So yes animals do have periods!
Not it is normal, so there is nothing to be worried about (:
Its fine so long as he/she is not on the website for long periods of time
Yes, that can be normal. Periods average 3-5 days in duration and cycles average 28 days. But, if your periods are so heavy that they become a nuisance, such as having to change your tampon/pad every two hours or even less, you might want to mention this to your doctor if this is the case.
13 is a prime number so the only factors are 1 and itself.
Go to see your doctor - there's medication to make you less likely to throw up, painkillers for the cramps, and also medication to reduce your flow if your periods are so heavy it causes problems for you.
13 is a prime so its only factors are 1 and 13. 13 is NOT a factor of 9, so the only common factors of the two numbers is 1.
if they have started their periods then yes, but I'm a bloke so I'm not really an expert
