it really could be either, since you had sex with both of them so close together
i just ranted about this on a different post and i dont feel like doing it again but please why wont people think before they go having sex with more then one person
it doesnt matter if you washed or not, the sperm is way way up there and nothing you do will get it out, you wouldnt even be able to vacume it out (although that is something i think would be funny to see someone try) and pulling out doesnt work either
the reason you had probably not gotten pregnant with him was that you two werent doing it at the right times
a conception calander can not tell you for sure, there are so many things that could screw up your ovulation
and an ultrasound can be up to 2 weeks off either way, so thats not completly accurate either
the only thing you can do is get a dna test
