Period or not a period??

Summer

I just recently got off the depo shot. My last shot was in January and was due again on April 2nd 2019. I decided not to go because me and my fiancé want to start trying for a baby. April 3-10th I had a period. I never had anything until Tuesday July 23rd. It started out as brown then the next day it was red. For a week it was going back and forth from brown to red. I had cramping with it, so I’m not sure if it was my period or what it was.
