I am currently 26weeks n 6days pregnant..want to know which month is going on? and the 7th mnth starts from 27th week or from 28th week?

A. The seventh month (weeks 25-28) -begins 24 weeks after the start of your last period. At the end of the month there are still 12 weeks until the birth (2 months, 24 days). At the beginning of the month the fetus is 22 weeks old and at the end of the month 26 weeks old.
