My gf menstruation cycle is 5-8th of every month, she took ipill on 15th july and had withdrawal bleeding for 3 days on 20th july night to 23rd july evening. Just for safety she took ipill, we have not had intercourse or oral, my wet (not cum or ejaculation) I was roused and wet was touched her genitals, so she took ipill. Took urine pregnancy test also all were negative. Now when her periods are expected? Roughly?
