Is it possible that people slipped in abortion stuff to make both Kathrine of Aragon & Anne Boleyn miscarry?

Question

some people can do that, slip poison into someones food, to make a pregnant woman miscarry. And given the circumstances with Queen Anne Boleyn and the people of England hating her. Kathrine of Aragon she kept miscarrying, maybe the duke of Buckingham asked one of the servants too.... He wanted to be king and with no heir to the English Throne....?
