From what I remember reading at age 43 the statistics are not very good, as something like >97% of the eggs are chromosomally abnormal. If one is able to get pregnant at that age, miscarriage rates are around 65%.
Obviously there are plenty of anecdotal examples out there of pregnancies for older moms. Though, usually at this age it is very difficult to have a successful outcome for most women.
I have a friend who struggled with this situation, she got married for the second time and really wanted another baby (she had three grown children from her first marriage whom she easily conceived). She did go the infertility route, however it did not work and they told her that at her age she should consider egg donation, however she was not interested in going that route.
