Divorcing a pregnant woman

Q:

1. A brother divorced his wife once, a talaq baain, then performed a new nikah. After that he divorced her as follows:

I hereby formally issue one talaaq baain to ..., on 28/03/1439 (17/12/2017) at 15:22 pm. I also make ta’leeq of another talaaq baain which falls on 28/04/1439, exactly one lunar month from now, thereby completing 3 talaaqs, according to what has been mentioned as the sunnah method of divorcing a pregnant woman. Is this the sunnah method of talaq for a pregnant woman.

2. Is it not repugnant to divorce a pregnant woman? Are there any ahadith for this?

3. After 3 divorces, does the son-in-law have to observe hijaab from his ex-mother in-law and is communication permissible?

Thoughts of kufr

Q: I live in Iran and I have problem with my life. Sometimes when I am playing games or prayer I always say bad words at Allah in my heart. I don't know what's wrong with me and I don't want to say things like that but it always happens... I'm scared because I am feeling like I'm a kafir by saying bad words at Allah. What should I do now? Am I a kafir?

Giving up sin

Q: If a person commits a big scene and asked for forgiveness from Allah by reading two rakats of salat of tauba and again he committed the same sin and again had read the namaz and seeked forgiveness from Allah for the same sin and promised the same that he/she will not commit that sin again, and again if he does the same sin then how should he overcome this habit?

Breaking one's fast due to fear of not being able to manage the fast

Q: Concerning the fast for Mondays, I went to sleep the night before intending to wake up to fast, then I woke up before sunrise and made the intention that I was not going to fast, and upon shutting my eyes I had once again changed my mind to fast thinking it is before sunrise and that I can do Sehri, however, upon checking the time I realised it was past sunrise and I was confused as to whether it counted as a fast or not, and I regarded myself as a fasting person and when another family member asked me regarding eating I verbally said I was fasting. However, I had a slight fear of not being able to maintain the fast throughout the day and therefore ate something upon making a judgement by reading some previous questions asked on a fatwa website. 

Therefore, Firstly was I counted as a fasting person in the first place?

Secondly, will making up the fast be necessary for me?

Doing Deeni work under the supervision of someone who is well grounded in Deen

Q: According to the Hadith "al Quranu hujjatun laka au alaika". If I go from place to place reminding my brothers and my self regarding Deeni tenets, will this ayat alone somehow be sufficient for my immediate salvation? Or will I be given the ability to fully act according to Deen by Barkat of this or any other ayat with steadfastness?

I am afraid you are going to answer that if I do not act on the remaining verses but stick to one Quranic verse, the bad will out weigh the good and the Quran will be proof against me.
