TMI but should I be concerned

Amanda
Alright ladies! The depo has really done a number on me! 
So late period for 30 days.
Water color period for a day.
Nothing.
Four days after water color experience.
Spotting. The brown kind mixed with a bit of fresh red.
Now I have a yellow liquid coming out. Like not sticky or thick like discharge. But yellow and watery and some brown stuff consistency of discharge. 
There's the nut shell. Should I be concerned or just wait it out?
