Read all about the first trimester and third trimester.
The second trimester -- the 14th to 28th weeks of pregnancy -- is often considered the best. The nausea and vomiting pregnant women often experience in the first trimester typically abates, and women tend to have that "pregnancy glow."

Baby's Progress

This stage of pregnancy is the main period of growth. By the 20th week, the baby is growing rapidly in length (approximately 25.5cm) and weight (about 340g).

The mother can now feel -- and you will be able to see -- the very active movements of the baby. The baby now has eyebrows, eyelashes, and hair on its head. By the 28th week, the baby has a relatively good chance of survival if born early. The baby's enzyme systems and other endocrine processes develop. The baby is about 37cm long and weighs 900g by the 28th week of pregnancy.

Prenatal Care and Doctor's Visits

As in the first trimester, there will continue to be several doctor's appointments to monitor both mom and the baby's health. You may discuss a birthing plan and attend childbirth classes together.

Sex in the Second Trimester

If a woman has had frequent miscarriages, your obstetrician will advise you on sexual intercourse. In some cases, they will suggest avoiding intercourse until after the birth of the baby.

Every couple experiences this trimester differently. Some women are easily aroused and want sex more frequently, while others may be too tired or worried that sex will harm the baby.

A pregnant woman's breasts are often tender and sensitive, and pressure may cause pain, so your technique may have to change. It's important for both of you to openly communicate your feelings.
