very possible, but a dna test will confirm this. the dates are very close.
doctor's can only estimate with a few days off, so you should consider the test to be 99.9% sure.

oh okay well they said my conception date is sep.3rd is that the day i became pregnant or is that how long it took cuz i kno sperm can travel 72hrs and if thats the case cant i jus count 3 days back and tell?

I think it would be your partner's baby because if you "supposedly" conceived on Sept. 3, it would of been from him. Although, I do have a question for you that's kind of personal. Were you using protection, or just the so called pull out method? I didn't realize you can get pregnant right after your period...I haven't been too careful, so I was just wondering what happen in your case? How far along were you when you found out you were pregnant?

It sounds like it is your partners baby, but if you get depressed, not eat right, or other things may throw your ovulation date off a little.
you had sex with your ex on aug26 and your current boyfriend aug 30, so that's the difference of four days, i really believe it could go either way.
are you able to test our ex to confirm it is or isnt his.
the baby is already born, did you put your boyfriends name on the birth certificate?

with my partner i wasnt using protection because he wanted this to happen. But with my ex he was doin the pull out method but its jus scary i'll no better next time if there is one i highly doubt...I didnt know you could either but i told the doctor my last period was aug.21 and he said my conception date was sep.3 i was 6 weeks when i found out i was pregnant. They say take your cycle days and subtract it from 14 and it equals to how long it take you to ovulate and count 14 days from your last period and thats your conception date ill do mine for an example for you...my cycle is a 28 day cycle so (28-14=14)then my period was aug.21 so i counted from aug.21 to sep.3 which was 14days and thats how i got my conception date....

and service u no the baby isnt here it will be may 28th 2010.....and the ex moved outta town havent talked to him so probably not but most ppl say they think its the partners and im thinkin so too it adds up more to being him.....
