Depo shot and periods

Pelita

So I recently started the depo shot and my first dose was sometime in April. I then got my period May 15 and hadn’t stopped bleeding/spotting since then. I got my second dose a few days ago and my bleeding stopped but i started spotting again. I know this is a side affect but is anyone else experiencing this on the shot? I just liked the idea of getting a shot than the Nuva ring, pills, or IUD.
