So is it still necessary to have a paternity test done if I had two sex partners? They estimated that I conceived march 3-5. I didn't have sex with the other guy in the whole month of February but I did between march 12-14.

In order to determine paternity (who the father is), you would be wise to ask for DNA testing of both men once the baby is born (and the baby will be tested too). Child support and visitation will depend on who is the biological father.

Dates are estimated and could be off as much as a couple weeks or more at times. So yes a DNA test is the best to be sure.
