PROVERA AND ANTI-ANDROGEN PILLS

V

I’ve had the first anti-androgen pills when I’ve had the first “withdrawal bleeding for like 7 days” when I stopped taking provera which is like a normal cycle but my brown discharge continues up until now Last dec 30 I’ve finished my 21 pills and I’m 7 day pill free and my Ob said that is where my menstruation come but now, I’ve had like spotting bright red mixed with dark brown. Is this even normal?. Ever since I took the first pill my bleeding is continuing up until now
