Long Story Short, Don't Judge. I Had My Period On

Long story short, don't judge. I had my period on the 7th more or less in march. I don't exactly remember if it was the first day or in between. I had sex with let's call him guy #1 on the 14th. Although he started off using no condom, he finished with a condom, thus ejaculating in it. So then I was with guy #2 from dates 18-27 continously having protected and unprotected sex and he ejaculated in me about 4 times. I then take a pregnancy test on the 2nd of April and it came out positive.  What are the chances of guy #1 being the one that got me pregnant even though he didnt ejaculate in me? (Maybe precum?) And if it were guy #2 wouldn't it be too soon to show positive?
