Family problems

Q: My mother is a widower since 18 years. She raised me her daughter and my brother on her own. I am married for seven years now Alhamdulillah. My brother is married for four years. He is involved in drug addiction. He has no child yet. My mum has money and good house but no happiness at all. Life is all scattered. She wants to ask what could be the reason for such situation?

Irregular bleeding

Q: How should a woman determine when to start praying after her menses? For example, if she has discharge for 3 days only so should she start praying after 3 days or she has to wait up to 6 or 7 days. What should she do if she thinks she has finished her menses and starts praying and then later she sees more blood or a brown discharge?
