Plan B!!!! Pregnancy question!!!!? - plan b urination

My girlfriend and I have had sex if some of my sperm fell to the ground and may enter her vagina, but not sure. To be sure we have a Plan B pill and it took about 7 days. Currently it has an increase in appetite, urine occasionally experienced frequent changes of mood and thinks it might PMS.
I want to know whether they can have side effects of Plan B pills because hormones.
