So, the emergency contraceptive can mess up your cycle for 2 to 3 months after taking it.  It messes with your hormones which can cause a dry vagina but your mouth would not be involved.  That's unrelated to anything sexually speaking.  Use good birth control/condoms for the next 2 to 3 months so that you are protected as you will not know when you ovulate again due to the plan b.  It tends to throw things off.  good luck
