I took plan B after sexual intercourse will it still work if I'm ovulating ? If so will my period be late?

In brief: Yes

It should work. Plan B has the same degree of effectiveness at any time during the cycle.
It is about 95% effective if taken within 24 hours of unprotected sex.

In brief: Plan B

Plan B is 75% effective if taken within 24 hours and it usually causes some irregular bleeding about a week or so later. Plan B is not a good method of regular birth control.
Time to use condoms and get on the pill or something else.
