Nikaah & Marriage Issues

Q:

1. I had a missed miscarriage at 8 and half weeks of pregnancy. I conceived at a late stage as I was blessed with nikaah much later in my life. I am much devastated with the miscarriage.

My question is, will the miscarried foetus go to heaven or it never existed (as if there was no rooh in it)?

2. Furthermore, I had a dnc done but after three weeks post procedure I'm still bleeding. Please advise on the process for salaah and Quraan. 

Q: I was the youngest of my 6 brothers and 2 sisters. My chacha and chachi didn't have a child of their own so they adopted me. The name on my ID card is not of my original father. Is this fine or should I change the name on my ID?

Q: I came across some information a few years ago, which I don't remember the source. I am now pregnant alhamdulilah and I would like to verify this information as I cannot find anything in my Islamic literature.

Is true that dua is accepted during childbirth/labour? If so, please can you provide any basis.

Q: Is it permissible to sell a children's blanket which will have some decorations, a name on it (e.g. Zain) and with it will be "Allahuma bismika Amooto wa Ahyaa"?

Q: If a situation occurs where only the mother or the baby can survive after 120 days of pregnancy, who should be chosen, the baby or the mother?

Q: If you invited for a walimah and wedding reception and it’s separate with no music etc. Is it permissible to go? Please advise

Q: How can we make sure that our children do not apostasize from Islam as we know that atheism and liberalism is rapidly spreading? What can we do about it at an individual level?

Q: I read that it is not an obligation for a husband to pay for his wife's medical bills, and that she must pay for them herself. How can a woman who has not gone to college or worked outside the home due to following Islamic rules get a job that will pay for her medical bill while also being sick? I do not understand how a Muslim women are supposed to cover their own medical expenses when Islam has discouraged them from working their whole lives? 

Q: When a woman is pregnant she usually has an ultrasound at each visit. Will it be permissible to keep the baby scan and show others? Does it fall under the same catergory as taking a CT or ultrasound scan of any part of the body?

Q: Because of my job I have been transfered to another city. Since I am married, my wife is back home.

My question is how long can one stay away from his wife without craving any sexual intimacy with his wife? Like for how many days/months. What does Islam says about it? As I live far away from her so it will take time to go back home.
