Posible paternity rights????

Arkansas- Four years ago I was living in Louisiana. Got pregnant, but I don't know by whom. Three choices. Had my son in Louisiana, moved to Arkansas when my son was two weeks old. Remarried, and now one of the ex-boyfriends is wanting to force me to have paternity tests done. I haven't requested anything from anybody. Can this person come in and force this even though I don't want it done? Please help me.

From what I've been able to find, Arkansas does not have a statute of limitations for determining paternity.
