Please don't judge me.. I had my period July 8 I have a 28 day cycle and my ovulation predictor says OD is on the 22nd of July... I had sex with guy #1 on the 22nd and he admitted he might have ejaculated a little I had sex with guy #2 second day and he did not.. I feel,like guy number one is the father but I'm just not sure and I would love a second opinion

Impossible to make any determination due to the time frames involved.
The ONLY sure fire method to determine paternity would be a DNA test with ALL the parties involved AFTER the birth.
