Her period ended then she saw some drops of blood
Question

                There is a woman who is 46 years old, who has some small fibroids in her uterus. Her period ended on June 20, and she started bleeding again on October 3, i.e., after three months and 12 days approximately. The colour of the blood is light red and it hardly comes out, hence she could not tell if it was menses. Should she stop fasting and praying or is this a case of sickness because of the fibroids?.
Praise be to Allah.The blood which means that 
    a woman should stop praying, fasting and having intercourse with her husband 
    is the blood of menses. Allaah has given it signs which are well known to 
    women. With regard to the colour, it is black; with regard to the smell, it 
    has an unpleasant odour and is also thick. Anything other than that is not 
    menstrual blood, rather it is the blood of istihaadah (non-menstrual vaginal 
    bleeding). This is what women call nazeef (lit. bleeding), and this bleeding 
    does not mean that a woman should stop praying, fasting and having 
    intercourse with her husband. 
From the description of the 
    blood and from the fact that it is so little, it seems that this is not 
    menstrual blood, and based on that she has to pray and fast, and it is 
    permissible for her husband – if she is married – to have intercourse with 
    her. 
We have mentioned the 
    differences between menstrual blood and the blood of istihaadah in the 
    answer to question no. 5595. 
And Allaah knows best.
