Personal question

So on Oct 19th I found out that I was pregnant with my first child . I went to the doctors Oct 22nd to confirm it . well I have been bleeding since Oct 5th I got an ultrasound and blood test done Oct 25th and on Oct 28th they had told me they didn't find anything in the ultrasound and that I may just be very early in pregnancy so they did another blood test and 3 days later they told me my hormone levels were dropping and that I was miscarrying . I just want to know how long you'll bleed because today is Nov 5th and I'm still bleeding ...
