NEW GJ placement question - help

[kQ123_]

Hello, had a pt with a new GJ placed. It was to gravity for a few hours and then was supposed to be clamped after. It had 75 mL of dark brownish/red output for the several hours it was to gravity, is this normal? Should I have reported to the doctor? I figured there would be some output since it was to gravity, but the oncoming nurse seemed confused by it. The GJ flushed great and had no issues after, but now I’m concerned about the output. It was not bright red blood and wasn’t quickly coming out or anything. Thanks for your advice in advance!
