hello
it will be difficult to diagnose paternity just on the basis of due dates & conception dates as they may not be accurate
from ur 3 September due date & 11 Dec conception date ur period most likely began 26 November .but conception dates can vary . as only 2 days difference in partners ( Dec 8 & Dec 10 ) so paternity cannot be accurately predicted in ur case

blood group of the child & father may indicate paternity in certain cases but again this may not be confirmatory .

for confirmation of paternity, dna samples of father & child r matched .
but for this u have to wait till the child is born

Meanwhile
u can also check for any lab which tests fetal dna from maternal blood in antenatal period
other procedures to obtain fetal dna in antenatal period r risky for the baby & hence not advisable

hope this answer helps you
