Considering the effect of her giving birth at that time in her life and career, I think it's safe to say that she probably made the right call and it was definitely her call to make.
No woman had a right to abort any unborn child. I can never understand why does people think that woman knows whats right for the baby and herself. For a woman to abort a baby is such a horrible thing for any one especially without discussing it with their lover or their husband or their bf. To me if i did that i will forever feel horrible and regret it for the rest of my life and would never ever want a child after i had commited something disguisting. If the baby is still moving in your belly than its alive whether people wanna agree with it or not.
If a woman would at least have some heart to let the child live then maybe things would be better. But no person has a right to abort a child whether your a man or a woman.
