After depo & not preventing

Hi there

So I'm coming off the depo and we're currently not preventing pregnancy.

I should have had my last depo on june 2nd, but I didn't go for it. I only had 2 depo shots so I was only on it for 6 months.

I'm not having a period right now, or at least I haven't gotten any...

I guess I just want to know when I should be expecting my period, could I get pregnant,...? When should I be testing if I don't get my period,...?

Before our baby I had the depo for 4 years, after the depo it took us 2 full years to conceive.. But also my body was waaay different with the depo now than before my pregnancy, so I feel like I cannot build on that previous experience for knowledge.. Or something...
