okay, so me and my FWB, decided to have sex in my car on Sunday. (July 24th). Unprotected...... My last day of fertile window, with a 8% of gettin pregnant.  Afterwards I took a Plan B pill and went on my way home.... , nauesa, sharp pains in my stomach here and there. Diarrrhia for a couple hours. (july 30). Im having no discharge . Barely its kinda cloudy but mostly clear (july 30) . Is it safe to say the plan b pill is working ?
