Newly Off Depo

So I've decided to stop getting my depo shot do to health reasons but specifically so I could get my weight under control. Just wondering if there are any specific side effects I should look out for. I've been on depo for 4yrs straight. Not really worried about finding a new BC since I haven't had sex in 11 months.

Idk what to expect period wise since I haven't had one in so long. For the ladies who have been on depo nd got off what was your experience once you were off the shot.
