Depo shot

I have a questions bc i am new to this depo shot.

So the first time i got on the shot i had my period, but now i don’t. I went and got a fill on the shot and now i don’t have it, but i get cramps & mood swings with it. is that normal? & gaining weight as well?

i don’t have my period but i still get everything but i just don’t bleed, i get the cravings, the cramps, and the mood swings but that’s about it. is that all normal?
