Nuva Ring

Adeline • Snowboarder, and Pre-Dent Student
I recently had a fling with a guy. I have a Nuva Ring in. Normally I'm paranoid about getting pregnant, and stress protection. However drunk me wasn't as careful as I should have been. Bottom line... He came in me twice with no protection besides the ring. 
My period should have started yesterday, but didn't. I have no bloating, or gas at all. One weird thing though, I've had creamy white discharg... Anyone know what could be going on?
