What month is the 28th week of pregnancy? The 28th week of pregnancy means that the 7-month pregnancy period has ended and the pregnancy has entered the 8th month. According to medical experts, the fetus can already sense external stimuli in the abdomen at this time and begin to respond to music, sounds, tastes, etc. Therefore, pregnant women should start to interact more with the fetus at this time, such as singing, talking, stroking the belly, etc.
