Im 9 days late on my period and im fainting and really dizzy. Could i be pregnant?

My name is Jennifer and I'm 19. For the past couple of days I have been feeling a little weird, but today I woke up and had a weird pain in my stomach, I have been fainting, really dizzy, and also im 9 days late on my period... Is it possible that I could be pregnant. Is there any kind of home remedy that can tell if your pregnant? I have no money to buy a pregnancy test. I would really appreciate any feedback. Thank You.
