Fasting of a pregnant woman

Q: What is the sharee ruling regarding fasting in pregnancy:

a. If a woman who is in her third trimester leaves her fasts fearing that she will not be able to bear the hunger and thirst and might end up breaking the fast, will it be permissible for her to miss her fast with this intention?

b. Is doctor's permission required to leave the Ramadan fasts in such condition? What if she is not able to consult a doctor as nowadays due to coronavirus doctors are hardly available.

c. If such a pregnant woman often suffers from nausea and vomiting and misses her Ramadan fasts thinking that she might not feel well, will it be permissible for her to do so?

d. Under what conditions will the pregnant woman be allowed to miss her Ramadan fasts?

Following the imaam in salaah over Skype

Q: During a special time like an epidemic, is it permissible to pray in congregation by following an imam over Skype? For example in Jumu'ah, if the imam delivers the sermon in Skype and leads the prayer, can the muqtadi take part in the congregation from their houses (which is different than the imam's)? Is this congregational prayer valid? If not, what is the basis of this invalidity according to Quran and Hadith?

Distribution of husband's private pension payout after his demise

Q: My husband passed away and we have been given the details of the inheritance which I have to the best of my knowledge and with what I have had in my control given to the inheritors. I have one question regarding his private pension, this was basically set up and usually the wife gets the payments if the husband passes away. Does this money then belong to just the wife or do I have to share it with all the inheritors? 

Husband making wife pay for household expenses

Q: I want to know if a woman should be doing all the payments for a man while he sends all his money to his family. I know women must assist but not pay for everything while the husband is saving his money for his family. My husband is religious; he reads namaaz 5 x a day. I love him very much. Because I don't have children he takes me for granted to be a slave and support him. Please tell me how how should I approach him without us having a problem. He always tells me that Allah subhanallah is happy with him and no matter how much wrong he do does, his 5 x a day namaaz will get his sins washed away. I don't want to break my marriage.
