Can your parent really get you take a test to see if your a virgin or not?

Is there really a test for this? And could you get your doctor to lie for you if there is? Cause thats not really something I want my parents to know and i mean im 17 but theyll kick me out of the house 100% and i really dont want that to happen...And is there anyway you can like fool you doctor into thinking your a virgin? Cause my friend Shelby told me there was a pill that you can take over like a week that will tighten you up uh, down south and youll seem like a virign. Help?/
