I Just Had My Baby On 01/05/16 My Actual Due

I just had my baby on 01/05/16 my actual due date was 01/02/16 ...I had 2 sex partners! My last menstrual period was 03/28/15 ..1 guy I had uprotected sex with maybe 3 times after my period before 04/14/15 . On 04/14/15 I had protected sex with the other guy whom I was not in a relationship with but I think the condom at have broken, is there any possible way he could have gotten me pregnant, and not my boyfriend?
