Semantics: A pregnancy is considered to last 40 weeks or 9 months. The two are not directly interchangeable because most months are not exactly 4 weeks. Half of a pregnancy is 20 weeks or 4 and 1/2 months. It just does not correlate evenly. Most of us use weeks rather than months to follow the duration of a pregnancy.
