How soon after missing one months injection by a few days can you conceive?

If you miss a monthly injection of a contraceptive, such as Depo-Provera, you may be at risk of conceiving shortly after. The effectiveness of the injection decreases the longer you go without it, and ovulation can resume within a few weeks after the missed dose. Therefore, if you have unprotected intercourse after missing the injection, conception could potentially occur soon after, depending on your individual cycle and timing. It's advisable to consult with a healthcare provider for personalized guidance.
