URGENT? Plan B??

Just realized in the craziness of finding out about his (27m) cheating I 23f forgot to take bc for two nights. F***. I packed a bag that night, brought my daily medications, and went to stay with my mom for support. I've been crying and busy with summer classes. I take it very consistently under normal circumstances.

Last took one pill around 11 pm Thursday, sex at 7 pm Friday no pull out right before I found out. Broke up Fri 11 pm. Just took a pill now 12:30 am Monday. I have taken MANY showers since to try to rinse him off me in general. Does anyone know if this requires plan b?

I had wild baby fever right up until I discovered my fiancée cheating.
