You are well into your third trimester and are probably starting to think about what life will be like with your new baby. At this stage, your body may be feeling the effects of being pregnant for more than seven months. You may notice many changes that have occurred. You may also be dealing with uncomfortable aches, pains, and swollen body parts. With just a handful of weeks to go in your pregnancy, you should know about signs of early labor and when to call your doctor.
Changes in Your Body
By now you are aware that many parts of your body change during pregnancy. While some are obvious, such as your growing mid-section and breasts, many more parts of your body have adapted to your pregnancy as well. The good news is that most of these changes should revert to normal after pregnancy.
During pregnancy, your body produces more blood than normal. Blood volume increases by more than 40 percent and your heart has to pump faster to accommodate this change. Sometimes, this can result in your heart skipping beats. If you notice it happening more frequently than every so often, call your doctor.
As your baby grows, pressure builds on your sciatic nerve, the largest nerve in your body. This can cause back pain called sciatica. To relieve back pain, you may try:
- taking warm baths
- using a heating pad
- switching the side you sleep on to alleviate sciatic pain
A study in the Journal of Orthopaedic and Sports Physical Therapy indicates that physical therapy, such as education and exercise therapy, can reduce back and pelvic pain before and after pregnancy.
If you are in severe pain, call your doctor.
Ankles and Feet
You may notice that your ankles and feet are swelling more than they did in previous months. That’s because your growing uterus puts pressure on veins running to your legs and feet. If you are experiencing swelling of the ankles and feet, prop them up above heart level for 15 to 20 minutes, at least two to three times daily. If you are experiencing extreme swelling, this could be a sign of pre-eclampsia, and you need to contact your doctor immediately.
With just seven weeks to go in an average 40-week pregnancy, your baby is getting ready to enter the world. At week 33, your baby should be about 15 to 17 inches in length and 4 to 4.5 pounds. Your baby will continue to pack on the pounds as your due date approaches.
During those final weeks in the womb, you baby will be kicking forcefully, using senses to observe the environment, and sleeping. Babies at this stage can even experience deep REM sleep. Additionally, your baby can see, with eyes that constrict, dilate, and detect light.
Twin Development at Week 33
You probably have noticed that your babies sleep a lot between all the kicks and rolls. They might even be dreaming! This week, their lungs have almost fully matured so they’ll be ready to take their first breaths on delivery day.
As mentioned above, you may be noticing some changes to your heart, pain in your back, and swelling in your ankles and feet. You may also be experiencing other symptoms in this final stage of pregnancy, including difficulty sleeping, heartburn, and shortness of breath.
Now that you are firmly in the final trimester of pregnancy, you need to know signs of early labor. Though your baby is not considered full term for several more weeks, early labor is possible. Signs of early labor include:
- contractions at regular intervals that are getting closer together
- lower back and leg cramping that does not go away
- your water breaking (it can be a large or small amount)
- bloody or brownish vaginal discharge (known as ‘bloody show’)
Even though you may think you are in labor, it could just be Braxton-Hicks contractions. These are infrequent contractions that do not get closer together and more intense. They should go away after a period of time and should not be as strong as the contractions will be when you finally go into labor.
Things to Do This Week for a Healthy Pregnancy
With the increased pressure on your body, it might be time to hit the pool. Walking or swimming in a pool may help swelling, as it compresses tissues in the legs and might provide temporary relief. It will also give you the feeling of weightlessness. Make sure to not overdo it when engaging in moderate exercise and remember to drink plenty of water to stay hydrated.
When to Call the Doctor
At this stage of pregnancy, you are seeing your doctor more frequently than before. Make sure to ask questions as you have them to ease your mind. If the questions are urgent, write them down as they pop up so that you don’t forget to ask them at your next appointment.
Call your doctor if you detect signs of early labor, experience unusual shortness of breath, or notice decreased fetal movement (if you don’t count six to 10 movements in an hour).
