Was 8 days late in September. Started spotting 2nd October so assumed it was af but its only lasted until today (4th October) Only 4 days! Is this normal? Have posted on here about a similar thing but concerned about the length of time and colour as it was a dark redish brown and ,especially as being late as i haven't had a proper period since august 30th. Pregnancy test done last week and bfn. Please help thank-you x
