Depo shot

Stopped depo shot in March still no period is this normal? I figured I would have had one by now haha. Is it possible to get pregnant without getting a period after the shot stops I feel like it's a hard no but I've never had birth control before so it's all new to me.

I'm also having a hard time losing the weight I gained from the needle any tip to help im on WW it worked in the passed lost 100lbs but gained 20 on the needle and it doesn't want to disappear I work out daily eating right but I still feel like I'm gaining instead of losing 😞
