My wife and I performed hajj a few years ago. During the hajj time my wife would have been on her periods. My wife was advised by a local female scholar to take "the pill" to stop her menstruating during hajj. She did indeed take the pills well in advance and continued the dosage as directed.
We completed hajj and returned. It has recently transpired that whilst she was taking the tablets during hajj, her "normal" period did not kick in, however she did experience discharge. The discharge was neither blood, nor was it transparent. It had a slight murkiness to it. She treated this as "istihaazah" and cleaned and bathed herself after every discharge to partake in any worship.
In the name of Allah, the most Beneficent, the most Merciful.
Discharge that is red, yellow, brown, green or black in colour is considered as haidh, however, discharge that is white is considered as istihadah. (Hidayah p.63 v.1)
Keeping the aforementioned ruling in mind, if your wife saw red, yellow, brown, green or black discharge it will be considered as haidh.
If the discharge she saw was in fact haidh then please email me again when did she experienced it and for how many days so that a more clearer ruling can be given in terms of her Hajj.
Only Allah Knows Best
