The Prophet Muhammad (PBUH) was single until the age of 25, and according to all historical documents and texts, he lived a life of ultimate chastity and holiness throughout these 25 years of adolescence and youth.

The Prophet Muhammad (PBUH) married Khadijah at the age of 25, and until his death, 25 years later, Khadijah (PBUH) was the only wife of the Prophet (PBUH).

It is noteworthy that the Prophet (PBUH) remained in mourning for Hazrat Khadijah for 3 years and did not take a wife, and in fact, Khadijah (PBUH) was the first wife of the Prophet among his wives who had the longest married life with him.

From here, the answer to the doubt about the Prophet's polygamy is given well; Because the Prophet Muhammad (PBUH) had only one wife from his youth to middle age, and three years after his wife's death, due to the political and social conditions of that day and the promotion and spread of Islam in the peninsula, he entered into multiple marriages.
