How many months is 16 weeks of pregnancy?

At 16 weeks of pregnancy, you are approximately four months along—using the standard definition where one week equals seven days and one month equals four weeks. You can calculate your gestational age this way, and you are now in the second trimester. At this stage, the fetus is relatively stable; however, attention to dietary adjustments remains essential. While ensuring adequate nutrition, meals should be light and easily digestible, and strenuous physical activity should be avoided. Most importantly, attend all scheduled prenatal check-ups on time—especially those key examinations, which require particular attention.
