Not sure who the father of my baby.

Hi, according to the nurse I am 7 weeks and 4 days pregnant. I am married for 5 years now. March 18 was my last period and it ended at March 21. I had unprotected sex with the hubby at 24 and 26 of March but I allso have sex with other partners on the 2nd of April (guy#1) and on the 7th of April (guy#2). Guy #2 told me he is physically not capable to make anyone pregnant cuz his MAN part crushed in an accident and doc told him he can't be a father again. (though Idk how truthful it is) and he didn't cum inside me. And with guy #1 I had sex on the 2nd and we used condom first time but second time he did some stroke without condom but didn't cum. Than on April 10th and 12,i had sex with husband again unprotected and the following week on the 17tn I did a pregnancy test which showed positive. I have very irregular period, so I used to maintain my period cycle through p tracker and according to the app I was fertile from April 9-14 & ovulation date was 13. Need to know when I got pregnant
