The woman who says late "M*A*S*H" star Wayne Rogers fathered her son is now going after his estate to get the huge sum she says she's owed ... a whopping $3.4 million.
Melinda Naud filed a creditors claim this week against Rogers' estate ... a follow-up to the civil suit she filed back in 2013. Naud claims Rogers begged her to keep it quiet after she gave birth to their kid, Luigi Calabrese, back in 1985.
Naud claims Rogers made a bunch of promises he never made good on before his death, including ... a $500,000 trust, a $1,000,000 life insurance policy, plus college expenses and child support.
Add it all up, and she says it comes to $3,418,000.
Rogers passed away on December 31, 2015 of complications from pneumonia.
