Is it dangerous to have a period that last a month?

If you're in the first 1-2 years of your period, it's normal. If not, call a doctor.

Yes, and it's a good bet that you are. No period = pregnant.

well some women can have there period last for several weeks and for a whole month.. so i guess its not bad.. ask your doctor in case.

Call a doctor. It doesn't.

Have a word with the nurse or your doctor, I've not heard of anyone having a period for a month, apart from after a miscarriage or having a baby. Get checked out and you'll get piece of mind.
