Hello doctors, my girlfriend is 20 years old have pcos, her periods cycle is not regular sometime it's 45 days,sometime 50days or sometime 60 days. we did just fingering. I'm not sure if it had precum or not,less likely but it did not have semen I'm sure of it. her last period was on May 1 and we did fingering on 15th may and today is19th june . till now she dont have any symptoms of pregnancy. and we did a pregnancy test almost 28 days after that fingering on 13th june, and it came nagative. I'm pretty sure before the fingering my hand touched many things like my shirt pant and her pants and underwear. please tell me if she might be pregnant or not? please hurry fast. we are very tensed thank-you in advance
