ANSWER:

Once you are certain of your purity and there are no colored discharges, you must take ghusul and start to pray. If brownish or yellowish discharges appear afterwards, you need to wash yourself and change what is affected with such discharges before praying and and making wudhu.

If these are continuous without stop, you are treated like having urine incontinence and you need only to do that after the athan and you can pray regardless of what comes out after cleaning yourself and making a fresh wudhu.

I got my purity in the form of dryness But when I do wudhu and check if there’s anything I see small dots of brown or yellow. Sometimes it’s a bit bigger and so I have to repeat my wudhu again. This repeats several times. What should I do as repeating wudhu like this several times causes many difficulties.
