"Heavily pregnant" is a phrase commonly used to describe a woman who is in the advanced stages of pregnancy. However, there are several alternatives to this phrase that can also effectively convey the same meaning. Some of these synonyms include "great with child," "in the late stages of pregnancy," "very pregnant," "well along in pregnancy," or simply "pregnant with a full belly." These alternatives can be used to avoid the repetitive use of the same phrase in a piece of writing or to describe a woman's pregnancy without stigmatizing her body by emphasizing her weight or size.
