Best Answer

21 weeks is roughly 4 months pregnant, and a pregnancy lasts for roughly 9 months, so you have about 5 months to go. Generally, though, pregnancy is calculated in weeks rather than months. A pregnancy lasts for roughly 40 weeks, so you have roughly 19 weeks left to go. Congratulations.
