Whitish discharge after haidh

Q: I am unsure of how to count my period days as, usually, even when I am not bleeding or on my period I have a small amount (the size of a two rand coin approx) slightly yellow/cream colored discharge or perhaps this may even be from sweat as I don't feel it coming out. So, when I count my period days, towards the end of my period about 8 days in, I see this yellow/cream color on my sanitary towel. Would this be considered as the end of my Haidh as it is the normal color that is always on my sanitary liner? Do I make a ghusl when I see this color or do I wait a full ten days. I am unsure as there is never actually no color on my liner, and, all of the masalas that I have read say that you have to wait for your sanitary liner to be completely white,but, I never experience that my sanitary liner is completely white.

Watn-e-asli

Q: I moved to a city for studies (a 7 year program) but never made the intention to move there permanently. During the course of the studies I got married in the city. From then on I considered the city to be my (second) Watan al-Asli, since I thought that it automatically became my Watan al-Asli since it is my wife's Watan al-Asli, although I still had the intention to move back to my original home after the end of my studies (together with my wife). Is this correct? I.e. is it my Watan Asli due to it being my wife's watan asli, or is it not since I never intended to settle neither myself nor my wife there? If so, will it still be my wife's watan al-asli even though she intends to move away with me from the city after I finished my studies?

Paper currency

Q: I am reading about the Quran and old Islamic economic system. Is it true that if any country or bank prints paper currency more than gold or silver reserves, it will be ribah or sin? Some Islamic teachers say that paper currency is a fraud because paper currency is more than Gold reserves, and in Islam money is which has intrinsic value like wheat, barley, dates, salt or gold and silver? 

Woman covering her head in the presence of other women

Q: On my wedding day I wore a maxi dress which was black in colour. I made up myself in a pleasant manner. But I didn't use a veil to cover my head or my chest. The important thing was no men was allowed to visit the place where I was. Only ladies entered the place. But my mother in law and sister in law made a big fuss on my wedding day saying that as a lady I cannot dress in that manner and they left the place without looking at our faces. The black colour of our maxi dress was a disgrace to them and they said that a bride cannot wear a maxi dress in black according to Islam. If we cover our awrah in a proper way without covering the head in front of only ladies, is it prohibited? Is it permissible to wear a maxi for one's wedding day in front of other ladies?

In-laws spoiling relationship between spouses

Q: My sister in laws have some misunderstandings with me. My in laws and mother in law used to say not to trust me whatever I do. They used to brain wash my husband. I myself expect love from them but they wanted me to respect and love them but they never do the same for me. They are making such problems which are big headache for me. Can in laws command my husband through wrong directions according to Islam?
