Can Whitish Vaginal Discharge With Odor After Taking Postinor 2 Indicate That The Pills Worked?

Hi, a girl had an unprotected sex with her man, and he cum inside her thrice. After that, she took 2pills of Postinor 2 within 6hrs of the sex. The next day, she started seeing a whitish vagina discharge with odor. Please, does that mean the pills worked? Will she get pregnant?
