Wanting to get pregnant!

Hi im 19 yrs old with a 9 month old & i was on the Depo shot for 6 months i stop taking it in February. I didn't get my period for 1 month & half ever since April i have been non-stop bleeding but its not heavy its medium, also its on & off like one day i bleed one day i dont. Me & my partner want another baby but with this irregular bleeding i dont know how long it will take for me to get pregnant or what help i need to do so !
