Is 2 week's between sex long enough to be able to tell who the father of a child is ?

Paternity: Yes. Usually. It all depends on when you ovulate and who's sperm was left in the vagina on the five days leading up to your ovulation.

No: The only way you can determine parental lineage when there was intercourse with 2 different men during the month of conception is through genetic testing of the baby, potential fathers, and yourself.

Not in court: Paternity can be suggested by timing but will never be accepted in a courtroom. It can be determined as early as 8 weeks into pregnancy by doing non-invasive testing.The NIPP is a test that takes fetal cells found in mothers blood and compares the genetic markers fount to that of prospective parents. It can also be tested after birth.
