Don’t stop until you see the flow of the blood.

I am confused regarding my menses, at the moment my lining is shedding (there is pieces of lining in the toilet after urinating) but there is no blood whatsoever? I was meant to start on the 14th but didn’t and noticed some faint brown discharge 2 days ago but again no blood at all. Should I do ghusl and continue fasting/praying or not? Sorry for the graphic information

My period is irregular and sometimes when it comes I used to see some drops or it’ll come in the morning and evening but at mid night I don’t see anything. This happens some days/weeks before its comes. I don’t know whether I should pray because it happens like this for 3 weeks now. I am confused of what to do.

if a girl is menstruating, can she help give ghusl to the dead body?
