"Why would I be having a heavy period every week 1/2 to two weeks? Sex is painful. I'm easily bleeding from other places as well, I bruise easily, my stomach is also constantly hurting."

There are a number of things that could cause this but more info is needed.

Is it painful? Did you go a period missing periods? How old are you?

I'm 23. It can be painful, but not always. And It's normally 3 periods a month.

You need to see your doctor right now. Something serious could be going on. When you say you are bleeding from other places that indicates something else entirely. Plus bleeding that frequent isn't right. You've got something that needs to be investigated right away. Go to your General Practitioner first and they can get you started in the right direction. Good Luck/
