It may feel as big as a whale as you begin your third trimester of pregnancy (which will last from week 27 to the end of your pregnancy)âlike you canât get any biggerâbut trust me; youâre about to! As your belly swells; your little one grows to between 6 and 9 pounds during this time.
Actually the third trimester begins at 28 weeks. It does not really matter what you call it. But I go with 27 weeks because in reality you are pregnant for 3 equal periods of 13 and a 1/3 weeks (or 13 weeks plus 2+ days). That math will give you 40 weeks. So really at 26 and 2/3 weeks (or 26 weeks and 4/5 days) you are 2/3 of the way done.
