The second trimester is the middle three months of your pregnancy. This is a time when lots of women tell the world they’re pregnant and begin to feel like the pregnancy is more ‘real’.
The second trimester of your pregnancy is from week 13 to week 28 – roughly months four, five and six.
As well as feeling and looking more pregnant during these weeks, you may also have more energy than you did in the first trimester. This will come as a great relief if you have been struggling with sickness, tiredness or anxiety about getting through the first trimester.
