My wife is in her 38th week, and at her weekly appointment today, her doctor advised her regarding the upcoming fast:
eat if you feel hungry; drink if you're thirsty. But definitely do not fast.
1 = what should she do as far as Tzom Gedalya ?
2 = what should she do as far as Yom Kippur ?
3 = What is the law regarding fasting if she delivers between now and Yom Kippur ?
