I had bleeding my first pregnancy with my daughter for almost 3months...
But mine was heavy but Dr said me and baby were fine... Not to be in your business but could it be a std ?
Before my heavy bleeding started my daughters dad gave me claumedia and I had brown discharge... Not to scare you and not saying you have it but make an appt to be on the safe side. Not good for the baby at all .
Wish ya luck...
Brown blood is usually old blood and usually nothing to worry about.
