I think my friend is only hurting herself?

My friend has been pregnant 7 times and never carried to ful-term. She usually miscarries within the first 3 months, but one fetus did make it to 29 weeks before she went into labor. it was stillborn. Her docs have told her that she will never carry to full term, there is too much scar tissue in her uterus. (I don't know from what) Now she is 28, financially secure, no reason that she shouldn't keep trying. Except that it destroys her and her husband every time she gets pregnant and loses the baby. I love her and want to see her have a child of her own, but I think that she's only hurting herself by continuing to try. What do you guys think?
