6 months pregnant = 22-26 weeks
The 6th month of pregnancy starts at 22 weeks. From 22 weeks to 26 weeks pregnant you are in your 6th month. The 6th month is the last month of the 2nd trimester. Enjoy this month while it lasts because at the end of this month many of the annoying pregnancy symptoms will return along with a few new ones.
I hated the whole pregnancy with Mini!
