I'm 17 and my period not supppose to come for 3 weeks. I'm have sharp pain in my vagina area its now a uti. What could it be? I would up and the pain keeps getting worse

If it's a UTI that's what's causing the pain. You say "its now a UTI." Do you mean it's NOT a UTI? If so, how do you know that?

You need to see a Physician. It could be a UTI or something more serious.

Are you sexually active?

Yes. And yes I meant not I been to a doctor.. but the pain is getting worse so I'm going back

Good idea - if it WAS a bladder infection it could now be a kidney infection.

But my dad keeps saying my pregnant. How do I deal with that? Cause I did have unprotective sex about a week ago but I know I'm not pregnant

Cause you can't get pregnant and have kow it after 1 weeks its impossible
