She had a miscarriage after two months of pregnancy and she is asking about the fasts she observed when she was bleeding
Question

                A woman started bleeding two days before she had a miscarriage, and that was in Ramadaan. She also bled for two days after the miscarriage. The foetus was two months old – should she make up the fasts or what should she do? Please note that she fasted and did not break her fast.
Praise be to Allah.If a woman miscarriages the 
    foetus when human features such as the head and limbs have not yet appeared, 
    and the outlines have not even appeared, the bleeding that occurs with that 
    is irregular vaginal bleeding, and it does not mean that she cannot pray and 
    fast. But if human features have appeared, then this bleeding is nifaas. The 
    earliest that the human features appear is eighty-one days (of pregnancy), 
    as is explained in the answer to question no.
    37784 and
    45564. 
If the matter is as 
    described, that the age of the foetus was two months, then the bleeding that 
    occurred before and after the miscarriage was irregular bleeding, not 
    nifaas. So the woman’s fasting on those days was valid and she does not have 
    to make them up. 
And Allaah knows best.
