Whenever women discover something men have always known, they begin to act like philosophers.
Microchemerism is a phenomenon women have tried to twisted into being the reason a child that's not their husband's biologically is either their unborn dead twin or someone in their ancestry.
Whereas it talks about behaviour and traits of old partners that can resort to affecting an actual biological child of their husbands.
Meaning that microchemerism is not the reason you want it to be to validate paternity fraud.
