What is required of a woman who intended to perform Umrah, then left the Haram without performing it, due to her doubt about being in a state of janabah (major ritual impurity) because of the discharge of a yellow fluid, then performed other Umrahs without having exited the state of ihram from the first Umrah due to her ignorance, knowing that she cannot go to perform Umrah now? And how can she exit the state of ihram, and what is her expiation? And are the Umrahs she performed later considered valid?

You erred by not completing the first 'Umrah after entering into ihram for it and returning to your country. What was obligatory upon you was to ask and seek knowledge. The second ihram is null and void because you did not exit from the first ihram. You have now exited from the first ihram by performing the tawaf, sa'i, and exiting ihram upon your return. As for the prohibitions of ihram that you committed before exiting, while you were ignorant, nothing is required of you according to the opinion of many jurists. However, if a marriage contract took place while you were in ihram, it is invalid and must be renewed.
