孕婦生理變化

現在起妳的體重增加應為每週1磅,這時胎動的感覺更強列。有些準媽媽因寶寶的向上推擠影響到胸腔而偶爾會感到肋骨處疼痛。

胎兒發育成長
這時寶寶的頭臀長為22公分,體重約有800公克。他(她)的眼睛已能夠睜開,並對光亮有反應,如用手電筒照射準媽媽的腹部,寶寶會自動地把頭轉向光的來源處。寶寶也會有睡眠與清醒的生理時鐘型態了。過了26週大的寶寶,若是早產,存活率會較高。

相關飲食
有些孕婦此時期易有貧血發生,請多吃含鐵豐富的食物,並應多食用含維生素C豐富的水果或蔬菜,以幫助鐵的吸收。

注意事項
由於寶寶腦部對明暗的感覺可經由母親得知,因此準媽媽應有良好的作息習慣,以免影響胎兒的生理時鐘。

How your baby's growing
Your baby now weighs a little under 2 pounds and measures about 14 inches, from head to heel. The nerve pathways in her ears are developing, which means her response to sounds is growing more consistent. Her lungs are developing now, too, as she continues to take small breaths of amniotic fluid — good practice for when she's born and takes that first breath of air. If you're having a boy, his testicles are beginning to descend into his scrotum — a trip that will take about two to three days.

How your life's changing
Around this time, your blood pressure may be increasing slightly as it returns to its normal pre-pregnancy range. (It was at a low from 22 to 24 weeks.) Though preeclampsia most often occurs in the last trimester, this is a good time to be aware of the warning signs of this dangerous condition that occurs in about 3 to 7 percent of all pregnancies. Signs you should be alert for include swelling of the hands and face, sudden weight gain (due to water retention), blurry vision, seeing spots before your eyes, sudden severe or persistent headaches, or upper abdominal pain. By checking for high blood pressure and protein in your urine, your caregiver will monitor you for preeclampsia at your routine prenatal visits, but call her immediately if you have any of these symptoms before your next appointment. Early identification of preeclampsia is essential for the health of you and your baby.

If your back seems a little achy lately, you can thank pregnancy hormones (which are loosening up your joints and ligaments) and your shifting center of gravity. Walking, standing, or sitting for long periods, bending and lifting can all put a strain on your back. A warm bath — or cool compress — might bring relief. Or you may want to schedule a prenatal massage by a trained therapist. Use a pregnancy wedge when sleeping, to support your back and abdomen. Try to maintain good posture, which will help reduce the strain on your back, and always take care when bending and lifting. If you experience severe pain or numbness in any area of your body, call your practitioner.
