Do you think?

Do you think there should be an amount of abortions a women should be able to have? Not talking about the kind a women NEEDS to have to save her life or if the baby will not survive/has severe deformities... I'm talking about women who do not use any type of birth control (I know, how would we be able to prove she was/wasn't using any) I know a women who has had 6, she isn't on ANY bc, and pretty much uses abortion as bc.
