Depo shot help

I got the depo shot right after having my baby. I got it march 26th. I started bleeding since May 30th and it has been non stop bleeding. It has been 3 weeks now and it doesnt seem to stop. I have to go back for the next shot june 26th. Which means that the shot will not be effective in 10 days. I will NOT get it again just because i hate the irregular bleeding. After my shot “expires” will the bleeding most likely stop??
