period after injection

well on april the 4th my injection ran out (thank god) i have only had it this once time but i bleed the whole way thru it with only a few days without bleeding, i know it can take a while for the injection to leave ur system i was just wondering about ur experinces if u had the injection like how long was it before you had ur period, cause im not allowed to get pregnant yet as it to early after my operation that why im waiting another few months, hopefully end of may start of july. have also posted this is trying for a baby. xx

thank you very much xxxx
