Pregnancy

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. 

Child remaining in the womb of the mother for more than 9 months

Q: In Behishti zewar theres one masala that states that if a husband passes away and then after a year the lady gives birth to a child, it will be attributed to him (she didnt get married again at all after his passing). Conception happens a few days as afterwards the nutfah dies and conception is only 9 to 10 months.

Is it normal for a mother to carry an offspring for 12 months?
