What's? : I'm not exactly sure what your question is. It doesn't sound like you're pregnant - you had a period since the encounter. However, a persistent discharge could indicate a possible STD. You may need to see an OB/GYN if the discharge persists or there is associated pain. Also may want to rethink your contraception plans if this will be an ongoing thing. Plan B too often not ideal for body!
