He divorced his wife thrice and he wants to take her back
Question

                I had an argument with my wife while she was in her early pregnancy and I said to her: “you are divorced, you are divorced, you are divorced”. Then days after she gave birth I said to her: “you are divorced” and during Ramadan I had an argument with her and I said to her: “I make you haram for me, I divorce you”. Is this considered divorce? Is it permissible for me to take her back, or she is now considered a divorcee?.
Praise be to Allah.
    Firstly: 

    If a man says 
    to his wife, “You are divorced, you are divorced, you are divorced,” it 
    counts as three divorces according to the majority of scholars. But if he 
    intended the second and third times as emphasis for the first, then it 
    counts as one divorce. 

    Some of the 
    scholars regarded his saying “You are divorced, you are divorced, you are 
    divorced” as being like saying “You are thrice divorced” and it only counts 
    as one divorce. 

    Your saying to 
    her “You are divorced” after she gave birth counts as one divorce. So this 
    was the second divorce. 

    But if she was 
    still in nifaas (post-partum bleeding) at the time of this divorce, then it 
    is a haraam, innovated divorce, and the scholars differed as to whether it 
    counts as such. The view favoured by the scholars of the Standing Committee 
    for Issuing Fatwas is that it does not count as such. 

    It says in 
    Fataawa al-Lajnah al-Daa’imah (20/58): Innovated divorces are of several 
    kinds, including: when a man divorces his wife at the time of menses, nifaas 
    or in a period of purity (i.e., not menstruating) when he has had 
    intercourse with her. The correct view is that this does not count as 
    divorce. End quote. 

    Shaykh Ibn 
    Baaz (may Allaah have mercy on him) said: Allaah has prescribed that women 
    are to be divorced when they are pure and free of nifaas or menses, and when 
    the husband has not had intercourse with them. This is the shar’i divorce. 
    If he divorces her during menses or nifaas or during a period of purity when 
    he has had intercourse with her, then this is an innovated divorce, and it 
    does not count as such according to the correct scholarly opinion, because 
    Allaah says (interpretation of the meaning):

    “O Prophet 
    (صلى الله عليه وسلم)! When you divorce 
    women, divorce them at their ‘Iddah (prescribed periods) and count 
    (accurately) their ‘Iddah (periods)”

    [al-Talaaq 
    65:1]. 

    What is meant 
    is when they are in a state of purity and the husband had not had 
    intercourse with them. This is what the scholars said concerning divorcing 
    them at their ‘iddah (prescribed periods): they should be pure and not have 
    had intercourse or be pregnant. This is divorcing them at their ‘iddah 
    (prescribed periods). 

    End quote from
    Fataawa al-Talaaq (p. 44). 

    If you did not 
    ask a scholar about the ruling on this second divorce then it does not count 
    as such. But if you did ask one who is qualified to issue fatwas, then you 
    must act according to his fatwa.  

    Your saying on 
    the third occasion “I divorce you” also counts as a divorce.  

    If a man 
    divorces his wife a third time, then she becomes irrevocably divorced from 
    him and she is not permissible for him until she has married another man, 
    because Allaah says (interpretation of the meaning):

    “And if he 
    has divorced her (the third time), then she is not lawful unto him 
    thereafter until she has married another husband. Then, if the other husband 
    divorces her, it is no sin on both of them that they reunite, provided they 
    feel that they can keep the limits ordained by Allaah. These are the limits 
    of Allaah, which He makes plain for the people who have knowledge”

    [al-Baqarah 
    2:230]. 

    It should be 
    noted that the nikaah al-tahleel which some people do, which is a 
    marriage to a second husband, intended to make a thrice-divorced woman 
    permissible for her first husband by means of the second husband divorcing 
    her, is haraam and the one who does that is cursed; it is also an invalid 
    marriage and it does not make the woman permissible for her first husband.
