Yellow or Brown Discharge following Taharah does not mean anything
Question :
If my monthly period started during prayer, what should I do? Do I make up for the prayer after the menstrual period?
Answer:
If the menstruation came after the time for prayer had begun - for example - if the menstruation began half an hour after the decline of the sun, after she had become clean, then she would have to make up for this prayer, since its time began while she was still in a state of Taharah. This is according to the Words of Allah, the Most High:
Verily, As-Salah (the prayer) is enjoined on the believers at fixed hours.
But she does not have to make up for the prayers she missed while she was menstruating, according to the words of the Prophet in a long Hadith:
Is it not so that when she is menstruating, she does not pray or fast?
There is consensus among the scholars that that she does not need to make up for the prayers she missed during her period. But if she became clean and there remained the equivalent of one Rak'ah or more in time, then she should pray for the time when she became clean, according to the words of the Prophet:
"Whoever caught one Rak'ah of the 'Asr prayer before the sun sets, has caught the 'Asr prayer."
So if she became clean at 'Asr time, or before sunset, and there was still time before sunset, or before sunrise, in the former case she would pray 'Asr and in the latter case she would pray Fajr.
