Seeing yellowish discharge when waking up

Q: My periods are always on time and even the bleeding will be for 6 days and I will take ghusl. Due to some physical ailments my regular vaginal discharge is yellowish in colour. It is like regular vaginal discharge but instead of white it is yellowish.

My question is, as this yellowish discharge is regular and after waking up from sleep I find this yellowish discharge daily, when I am certain that I didn't have any wetdream during sleep then what should I do? Is ghusl necessary due to this yellowish discharge which is continuous during the day as well as during the night.

Note: I am certain that there was no wetdream or lust during sleep.

Clear discharge

Q:

1. Does clear discharge break your wudhu? 

2. Whilst performing my salaah I discharged a clear discharge, does this mean my salaah is broken? Does this mean that I have to break my salaah and perform a new wudhu?

3. If I find out that I discharged after I have already completed my salaah, do I have to perform my salaah again?

4. If I have been discharging a clear discharge a lot the entire day, do I have to still continously perform a new wudhu everytime?

Selling food from home

Q: My mom does a private catering business from home and sells food from our house to the customers. Recently a food organisation has contacted my mom for her to sell weekly food to them so they can serve their customers this food. Is this allowed in Islam? Because the customers of that organisation don’t know who makes the food (if the organisation makes it or someone else) My mom is saying that it doesn’t matter where the food comes from because when you go to a restaurant no customer asks who cooks the food and where it comes from?

Custody of child if the mother remarries

Q: Please advise how a young widow with an infant child will cope with the following situation:

Her society and customs and practices require that if she marries anyone, her infant child will be taken away by her in-laws. Her father will not approve of any marriage, even if it is with a Muslim, if he is not from the same country as her, even if the man agrees to keep the child with his mother whom he will marry. The infant will be deprived of his mother’s love if she marries any man of her family’s choice. Staying single means she runs the risk of committing sin (maybe zina) which she does not want. In this situation, as she is an adult widow and not a virgin and has physical needs, can she not undertake a secret marriage?
