Can boys have periods?

Yes, some boys will menstruate.Some men have a vagina, uterus, and ovaries so will menstruate just like cis women do. Remember that not all men have a penis, and some men have a vagina.Cis men do not have periods or "that time of the month" - menstruation is a specific function, it is not just women being moody and getting menstrual cramps. It's sexist to suggest that women's menstruation is just their being moody and cramping, neither of these are a normal part of menstruation but part of a social construct around menstruation or a result of hormonal imbalance.
