I think that the pressure from the bra being tighter on the one side might make it leak more, more leaking more filling and on and on!!
Any pressure on the over gourged and swollen breasts will make them leak.
Maybe you could find even a bigger bra or one of those really stretchy one made just for pregnancy. Or nursing bra.
I hope this will help you
