Sorry, the dates are too close together.  The only way to determine paternity is with a DNA test.

when i did it with my ex on jan1 i was just finishing my period

That doesnt change the situation because a women can concieve (conceive) at any time during her cycle (atypical ovulation, sperm can survive in the uterus for about 5 days, etc.)

you would of gotten pregnant on jan 11 2010 and you due date would be oct 18 2010 that would make you 6 weeks 5 days

i didn't know i was pregnant all of january i just found out 2 weeks ago and before that i was drinking alot and partying and not eating right so i'm thinking maybe it is my ex bf and it's small cuz of that or if it's the other guy then it's a little big..idk what to think
