have you had an ultrasound since you had the brown discharge?? Because my doctor told me not to worry about the brown discharge and I went in for an ultrasound Just to be sure and i had miscarried. i never had bright red blood.
Bleeding is never considered normal untill cleared by a doctor. Once cleared by a doctor as not being dangerous, there are then many "normal" reasons to bleed. I spotted brown blood my entire second trimester.
