What is the ruling regarding my previous prayers in which I omitted some verses of Al-Fatiha due to haste? Do I have to make them up, or is expiation required of me?

If a woman doubts that she has omitted a letter or a verse from Al-Fatihah, but is not certain, then her prayer is valid and she is not required to repeat it; because the apparent (ruling) is its completeness. However, if she is certain that she has omitted a letter due to reading quickly, then the prayer is not valid and must be repeated; because Al-Fatihah is a pillar, and omitting a letter from it invalidates the pillar. If the omission occurred after its designated place, then the prayers in which this occurred must be repeated, with their number estimated if unknown.
