It is time for my period and all that is coming out of my vagina is this brown stuff. Is this bad, what does it mean?

I wouldn't worry too much about it. The blood being brown during your period is because the blood has stayed too long in your vagina wall. It usually happens during the 1st days of your period or last. It's just old blood :) If you're still worried about it, there is no shame to ask your doctor, but like I said it is not uncomon.

How old are you, do you have a mom or aunt you can talk to. Not that we don't love to answer you, but young girls should never feel bad about talking to their adult female family about issues.
