Q: I am 52 years old and went into menopause last year. I started to spot (brown) last night after Eshaa. This morning almost nothing. What do I do as I do not want to miss a fast unneccessarily?
A: You continue fasting until you see red/blood colored discharge. If that last for three days, then it is considered as haidh.
