She pregnet and says she haveing a constent headach what do i do?

I'm concerned: This is a situation where the person you are talking about should see her doctor right away. Depending on the stage of pregnancy and other risk factors, a constant headache can be not so serious or very serious. I highly suggest she go see a doctor. They will likely check her blood pressure, do a urine test and make sure it's not something like preeclampsia which is a serious condition.
