Depo Shot & my period this month

So this is the first time I'm on birth control. I decided to get the depo shot because it seemed the easiest. Now.. I'm just wondering, will I get my period this month? I got it 2 weeks before my period. I did have unprotected sex 4 days after I got the shot, but no symptoms of pregnancy. I get a little bit of pain & feels like Ima get my period. But it's not here 😐 I'm just really wanting to know if any of you got their period the month they got this shot.. ? ._. Tbh.. It hurts a little & from time to time but acne is gone & just a bit bloated. 
Is this normal?
