你怀孕的第二个三个月

Most women find the second trimester easier than the first. Hopefully, you’re feeling better and have more energy. There are big things happening during this middle stretch and it’s important to understand what to expect.

How Long Is the Second Trimester?

The second trimester spans 15 weeks, from week 13 to 28. Don’t forget to celebrate your half-way point, at week 20!

What to Expect During the Second Trimester

During the second trimester, both your body and the fetus continue to grow. Your baby is getting larger and stronger, and your belly is likely starting to show.

What’s Happening to Baby in the Second Trimester

By the end of the second trimester, your baby is 13 to 16 inches long and weighs about 2 to 3 pounds. She is fully formed and really starting to grow in height and weight. Her organs are wholly developed and she can hear, swallow and move around. She has a sleep cycle (which unfortunately may be different than yours).

在24周出生的婴儿可能会生存在一个neonatal intensive care unit (NICU).

Second Trimester Prenatal Care

You should see your doctor every two to four weeks during your second trimester. During your visits, your doctor continues to check the health of you and your baby, including:

• Blood pressure
• 胎儿心跳
• Growth, size and development of the fetus
• 眼底的高度（子宫顶部）
• uteru大小s
• 症状或不适

此时，在超声波上，您的医生可以告诉您是否有一个男孩或一个女孩。

第二个三个月清单

It’s important you take the best care possible of yourself and your developing baby. Continue taking your prenatal vitamins, exercising, eating a healthy diet, and drinking lots of water. Also, work on strengthening your pelvic floor by doing Kegel exercises and keep up a good dental hygiene routine. It’s also time to start preparing for birth.

Preparing for Birth

The second trimester is a great time to start planning for your delivery. Not only does being prepared help make the third trimester less stressful, but right now you’re probably feeling more energized and mobile than you will in a few short weeks.
