35 weeks pregnant

I'm going to be 35 weeks pregnant tomorrow (monday) with baby #3 and I am having some brown discharge to the point I've been wearing a pad. I mean let's be real, I've been wearing a pad half the time anyways because baby sits so low my bladder apparently doesn't get emptied fully every time and im tired of changing my pants. But if it wasn't for the pad I wouldn't really even notice the discharge honestly.

My question is, is this normal? I never dealt with that either of my last 2 pregnancies so this is new territory for me. If it gets worse or concerning I'll definitely call my dr but I just kind of thought with all the ladies on this app maybe someone else could give me some insight in the meantime.

Thanks in advance
