Trying to conceive

So my last depot shot was back in in May and I haven’t received my period yet and to me this is not normal usually when I get ready to start my period show up right away after Depot is close to being out of my system and it’s been a week now and I have not received my period. I’m trying to conceive my last baby and I have yet to see my period and I am facing premenopausal symptoms as well so I don’t know if that was it. Did you guys help me out, please and thanks for the advice
