Brown discharge is completely normal, as it is just old blood, which I would worry about, as long as you don't experience other symptoms along with it.
I've had no pain or swelling etc. But I do wonde because it's more brown sometimes than it is green. Is this odd?
Brown discharge is completely normal and is just old blood, though green discharge can be a symptom of something else, but doesn't always have to be. At times that discharge can be normal as well with certain hormone fluctuations. I wouldn't worry about it unless it begins to give you problems and there are other symptoms involved(begin to get itchiness, swelling, different odor, pain, or anything else).
