Gifting a property to one's only daughter during one's lifetime and distribution of inheritance

Q: I have only one daughter. I own a house and no bank balance.

1. Can I gift the house, my complete property to my daughter in my life and give full control over it to her? Can we stay with her in that house only after giving her the full control over it? I have heard that a gift can be given from 1/3rd of the property and a gift can be given to non heirs.

2. If I don't give the gift, what will be the shares of my only daughter and wife?

3. I had two brothers and two sisters out of which one brother has passed away. So what will be the share of my remaining brother and two sisters in my property?

4. Will my nephews and nieces inherit from my property as their father is no more?

NOTE: Please answer all these questions in the light of my case as I have only one daughter and no sons.

Woman following a tuhr cycle every month

Q:

1. Do women have to follow their tuhr cycle every month? I do not have a fixed tuhr period. Some months it is 20 days, 21 days, then another month 16 days. I may get a same tuhr period for two months sometimes. But most of the time it is unfixed. For years I am counting my periods like this - if I get a bleeding after 15 days from the last period, I treat it as period. Can you please tell if this is the correct way of calculating periods or do I have to follow my previous month’s tuhr period?

2. Almost a year ago. it happened that I forgot my habit of period. I forgot how many days it was. After much contemplation, I felt that my habit was 8 days. Since then, I have been practicing upon it. Is that correct?
