Me And My Fiancee Went Out. Even Though We Did

Me and my fiancee went out. Even though we did not have sex we rubbed it. Then I took IPill I was in my periods then. I have PCOS. So after I have missed my periods for two months. Light period where you even don't need a pad happened for 2 days during this two months. I have done some home made pregnancy tests and all results are negative. More over I have gained weight as well as had a lot of anxiety in the pass month. Can you suggest what is to be done?
