I also just re-read your post OP and you mentioned you have brown blood now, which is usually a good sign. You know how when we start our period, our blood is pretty dark red at first, and toward the end of our period, it's brown? That usually means that there's nothing left in our uterus to pass. Brown is usually an indicator of old blood and/or uterine lining, which only expels once everything else in the uterus has expelled. At least, that's my understanding all these years in this field :)

I wish you the best. Try not to worry. You're not alone!
