the weirdest AF

y
This was my first period off BC. It came about a month and a few days after I stopped. 
It also came at a time with a lot going on. It's the end of school so I am/was preparing for big presentations and finals along with the stress at work at this time of year along with traveling for the first time in a plane across country by myself. I was very nervous about the plane thing with all the stress. I received spotting Wednesday (night of presentations) the Tuesday in the morning (5am) had horrible cramps and it looked like a got it for sure. But the rest of the day really nothing happened. I felt fine. Then Friday the day I left on the plane I didn't really get much other than the morning. 
The rest of the weekend I was at my hotel I didn't get anything other than the brown stuff after a period only in the morning and nothing after I woke up. 
Is this something that is normal for the first after getting off ?? 
I didn't have any of the pain or the effects that come along with AF like I usually get.
