**Core Concept:** Diaphragm is a contraceptive method that is an intrauterine barrier method and acts by blocking the cervix. It is used for contraception and is typically inserted by a healthcare provider. Contraindications are situations where the use of diaphragm could lead to an adverse outcome.

**Why the Correct Answer is Right:** Option C, "Women who wish to become pregnant soon," is not a contraindication for diaphragm use. These women can still choose diaphragm as a contraceptive method while planning for pregnancy within a reasonable time.

**Why Each Wrong Option is Incorrect:**

A. **Allergy to the contraceptive drug:** Contraindication due to potential allergic reactions to the diaphragm components or spermicidal jelly.

B. **Pregnancy:** Diaphragm is contraindicated during pregnancy as it can affect the fetus and cause adverse effects.
