Depo Shot

Hello there mommies.. Magtatanong lang po sana ako, nanganak po ako last July via ecs and now 5months na po si baby.. Nagpainject po ako for family planning (depo shot) last September 08, 2020 and then may nangyari po saamin ni LIP ng November 16, 2020.. Tanong ko lang po kung safe po ba ako that time? I mean hindi naman po siguro ako mabubuntis ulit kahit hindi po withdrawal?? Salamat po..
