Kung nagpainject ka po na may regla, effective na po agad yan. pero kapag nagpainject ka po na walang regla, kailangan po muna magcondom in the first 7 days after ng injection, then after non, safe na. siguraduhin lang po na lagi po kayo nagpapainject pag nakaschedule, if every month or every 3 months.
contraceptive yan thats the main purposed it should be safe
