Hay, I'd definitely ask your OB about this one kasi it really depends on the type of injection you got and how your body is healing, some contraceptives ay okay na after a few weeks, pero iba't ibang timeline para sa iba! A few of us mums in my circle got confused about the same thing, kaya better to confirm directly with your doctor para walang worry habang nag-eenjoy ulit kayo. They'll give you the exact timeline based on your specific situation.
