I had my lmp on 5/21/13. i had sexual intercourse on 5/31and 6/1-6/4, with different persons. i found out that i waspregnant on 6/22/13. how do i find out whose baby did iconceive?

A paternity testing: Is the only way to determine the father of your child. Best wishes!

Genetic testing : Although i’m not a fertility specialist, i would inquire as to whether your period on 5/21/13 was normal in terms of timing, duration and amount of flow. If you had sex on 5/31 and 6/1- 6/4 with different persons respectively, i would think that genetic testing is the only way that you are going to successfully delineate the father of the baby. Consult your OB gyn for a definitive analysis.
