period after depo?

Alexandria

i have a quick question, I was due to renew the depo shot nov 28th and I had bleeding 18th through the 29th of this month (dec) it was almost like a period but very weird light and brown but red and brown when wiped away?

is that withdrawl bleeding or a period?

also had a cyst in my felopian tube attached to an ovum so maybe that indicates a period idk?
