My girlfriend have pcos. her periods cycle isn't normal.. sometime its 45,50 or 60 days. her last period's first day was on maybe 28th april to 2nd may we aren't sure. we didn't have intercourse but we did some fingering on 15th may. I'm sure its didnt have semen because i ejaculated after 30-45mins. but I'm not sure if my finger had precum on it or not . cause it touched my self before that. after 29th day of fingering (13th june) we took a urine pregnancy test it came negative and we took a test again after 6 days on 20th june it came negative too. we are worried because her periods hasnt come yet . she took povera for her periods for 5 days and its been 6 days from her last dose. but both test came negative what are the chances of her pregnancy. please tell. we are sooo worried.
