Stopped the depo shot!!

Hey mamas, I’m 10 months PP, and I stopped the deposhot back in December when it was supposed to be my next shot. The question is…does anyone know or been tru this…how soon would I get my period, also i would like to get pregnant again, because we want another baby so they can be close in age…but I have no luck, and I feel is because of the deposhot effect also all I do is breastfeeding…any help here LOL
