The “honeymoon period”, the span from week 13 to week 27 of pregnancy is when nausea subsides, emotions even out and sex drive returns. It’s also the time when you’ll start to feel the baby’s first movements. However, what to expect during the second pregnancy trimester?

Usually, the second trimester is considered to be the most comfortable between all three trimesters. Most of the early pregnancy symptoms will disappear in the second pregnancy trimester. You will have more energy, your breasts will get bigger, your tummy will start to look more like you are pregnant, and you will get your sex drive back again.

When Does the Second Trimester Start?

Pregnancy lasts for 40 weeks and the weeks are divided into three trimesters, each trimester has three months. As for the second trimester, it starts from week 14 and lasts through the end of week 27 of pregnancy.
