Preggy

Possible po bang buntis ka na, pero dinatnan ka parin? Had sex with 1st guy mga 3rd or last week of April. Had sex with 2nd guy last May 9 ng umaga and dinatnan ako ng period for 3 days (May 9-11) Had sex again with 2nd guy mga 3rd or last week of May. My EDD sa unang ultrasound ko is Feb 19, 2020 Can anyone guess kung kay 1st or 2nd guy ba to? Thanks
