I had sex feb 14 had a normal 7 day period feb 15 i had sex again march 1 my due date is november 22 is it likely to tell whom the father is?

By due date calculation then the conception was on February 14 which seems impossible because you had had a normal period of seven days before you had sex again on March 1st. So if you deliver a full term baby before December then DNA test has to be done in order to confirm the baby's father. Good luck.

You should know who you had unprotected with on both dates. The FEB. 14 date with a period the next day reveals the egg was not fertilized. The March sex was during ovulation which lead to your pregnancy. Knowing your partner is the answer, but a DNA test will solve all answers and determine who the father is.
