Period late

My boyfriend and I had sex the weekend of Memorial Day and I took plan b on Memorial Day (the 31st). I had a three day what I’m assuming is a “withdrawal bleeding” from June 7-9 but have not gotten my period yet. I did take the plan b right before my fertile week so I wonder if that affected my cycle. My period is two weeks late now but I am seeing some regular about to start my period discharge/wetness and the PMS symptoms. Should I be worried? That withdrawal bleeding was heavy and had clots like the first couple days of a regular period. Me and my boyfriend did have sex on June 27th, once he came completely outside of me and the other time I never came/neither did he because my hips started hurting.
