Are white, watery discharges after the menstrual period considered nullifiers of ablution, and is it necessary to wear a sanitary pad because of them, given that they may cause embarrassment at work? And does the presence of yellow discharges invalidate the ablution while wearing the same undergarments?

If a woman, after purifying herself from menstruation, sees white discharge, she is pure, but it invalidates ablution (wudu'). There is no need to guard against it because it does notSoil clothes. If it is continuous, she should perform ablution for each prayer after its time has begun and then pray the obligatory (fard) and supererogatory (nawafil) prayers. As for yellow discharge, it is considered menstruation if it occurs during her regular period; otherwise, its ruling is the same as that of white discharge.
