Your Pregnancy Week 25

Reviewed by James Brann, MD
Learn about your symptoms and changes during the 25th week of pregnancy.

Your Baby

By the time you reach pregnancy week 25 your baby probably weighs in at more than 1.5 pounds and may be almost 13.6 inches or longer! Most babies' length and weight tend to vary from this point on in your pregnancy. Keep in mind that while some babies are born a mere 6 pounds, others weigh in closer to 10 pounds! Most babies average about 7-8 pounds at birth.

Changes in Your Growing Baby

Your baby is working diligently on putting on weight. At this time your baby's spine starts to mature and blood vessels form in the lungs. If you were to peak inside at your baby you would also find her nostrils developing. By the end of this week they will even open!

Your Body's Development

Your uterus has grown to roughly the size and shape of volleyball. Your growing uterus may place some pressure along your back and pelvis. Some women experience sharp or shooting pains down their lower back and legs resulting from this pressure. These pains can sometimes become more aggravating as your uterus continues to grow.

Other women may develop sciatica during their pregnancy. Sciatica often results when the baby's head presses along the bones in the pelvis. This can compress the nerves located in the lower legs and back resulting in pain in these areas and even the buttocks. Other women will experience some numbness or a tingling sensation in their legs.

Sciatica pain at 25 weeks pregnant can be very uncomfortable for some women; many find they aren't able to walk or move their legs without experiencing severe pain. Fortunately all of these aches and pains are often relieved the moment after delivery. In the meantime there are several interventions that may help alleviate pain. These include applying hot or cold packs to the affected area, engaging in physical therapy or chiropractic care and massage, use of support cautions and limiting your range of motion temporarily until your symptoms improve.

While frustrating as with most pregnancy symptoms sciatica is often relieved entirely a few days after the birth of your baby.

Changes in Your Body

By the time you reach 25 weeks pregnant you are a magnificent and glowing specimen. Your tummy while big is not huge and bulky, and for the most part you are probably enjoying the attention everyone is offering you during pregnancy. Many women are shocked to find just how courteous and helpful many people are during their pregnancy.

If you have young children they may be curious about the baby in your tummy. Many women decide to hold off telling their children until they are closer to delivery. Most children have no sense of time hence have a hard time understanding that the baby will not come for several more weeks yet.

During your prenatal visit you should talk with your doctor and become familiar with the symptoms of pre-term labor. There are several warning signs you should be aware of that include:
  • Persistent and rhythmic cramping in the lower belly
  • Contractions that come more frequently than 4 in an hour
  • Cramping accompanied by low backache
  • Watery or bloody discharge or leaking

If you are experiencing any of these or other uncomfortable or unusual symptoms be sure to contact your doctor immediately. Your doctor can often take steps to prevent delivery if premature labor is threatened. The longer your baby stays inside of you in most cases, the better her chances for survival.
