Dark discharge (like the end of a period) normal after a sweep? TMI

Morgan

Lost some chunks of my mucus plug on Wednesday/Thursday (no blood). Got a sweep done yesterday morning at 39+6, had some dark red/brown discharge and some brown spotting for the rest of the day. Also had some long ropes of red/brown discharge I assume was my bloody show? As of last night and this morning there’s not as much in my underwear but when going to the bathroom I can see I’m still dropping pieces of brown discharge. It looks exactly like the last day or two of a period, is this normal? I was prepared for spotting to mean red blood lol so is this old blood my cervix thinning? Or just normal after a sweep?
