Family planning decisions are highly personal and should be made based on an individual's or a couple's specific circumstances, values, and preferences. There is no universally "right" or "wrong" time to engage in family planning, and it doesn't necessarily have to be tied to marriage.
Many people choose to discuss family planning before marriage or even before entering a committed relationship. This allows them to understand each other's goals, desires, and expectations related to family size and timing.
It's important to make informed decisions about family planning, considering factors like financial stability, career goals, and personal readiness for parenthood. Some may opt for contraception methods to prevent unintended pregnancies, whether they are married or not. Ultimately, what's right is what aligns with the individuals involved and their life circumstances.
