Uy, mama, this is actually a medical question na kailangan mo talaga tanungin ang doctor mo or go to a clinic ASAP, hindi ko kaya sagutin to with certainty kasi depends on your specific situation and the exact guidelines for your injectable. Kahit na medical field ang hubby mo, better safe than sorry talaga sa family planning, better na klaruhan with a licensed doctor or nurse ang timing and protection needed para ma-ease your mind completely. A few of us moms learned the hard way na it's always worth the quick check-up call para sa peace of mind! Hoping everything's okay na with the health emergency din, take care!
