The third trimester of pregnancy typically begins at week 28 and lasts until the baby is born.

The best way to keep track of fetal movement during the second trimester is to take note of the times the baby is most active. This can help to ensure that the baby is getting enough movement and that any potential signs of distress can be addressed.

It is recommended to start thinking about childbirth classes during the second trimester. Most childbirth classes are offered around 28-32 weeks of pregnancy.
