help please!!

i didn’t have my birth control in (nuvaring) and me and my man had sex a week before my period was supposed to start. we were drunk and not thinking much of it, and he came in me. i sat there for a minute to put clothes on so i could go try to pee and get it all out. then got up, and i felt it dripping out and pouring out. i didn’t pee, because i didn’t have to and i couldn’t force myself because there was none. i thought i got most of it out. AF was due the 17th and still not here. but i’m wondering if i just put a nuvaring yesterday, and took a test maybe today or tomorrow, would it mess with the PT?
