I thought I was losing my plug


I'm 37 weeks and 3 days. Yesterday morning I had some clear mucous when wiping. Not like a chunk but kind of like the start of a period discharge. Then last night I had the same thing but it was brown tinged. So I thought maybe it was the start of it slowly coming out. Over night I've gone to the bathroom a few times and haven't had anything else come out. Is this normal? Is it still slowly coming out or is it done??
