Nikaah & Marriage Issues

Glad tidings in the mubaarak Ahaadith for a lady who had a miscarriage

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. 

Authenticity of a hadith regarding duas being accepted during childbirth/labour

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.

Husband not obliged to pay for his wife's medical bills

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?
