What Is Third Trimester?
The entire nine months of pregnancy, i.e. nearly 40 weeks of pregnancy are usually divided into three trimesters. Talking about the third trimester weeks, it includes 28th to 40th week of pregnancy. In simple words, it is the last three months of pregnancy and thus the most crucial one.
This third trimester of a pregnancy can be both mentally and physically challenging for a woman owing to the final growth stages the foetus goes through. In general, the foetus development is over by the end of week 37, and after that, you may become a mother anytime and knowing what all you can do and expect during this period can actually do the needful.
Third Trimester Pregnancy Symptoms
The third trimester of pregnancy is that point of pregnancy where maximum care and precautions need to be taken. A woman may feel pain, anxiety, and even swelling around some areas.
But the following are the major symptoms you need to look out for when stepping into the third trimester of pregnancy:
- Increased foetus movement sometimes in the form of what you may call as kicks.
- Stiffening of the uterus aptly known as Braxton-Hicks Contraction may occur, but they are not usually painful.
- Frequent urinal discharge will make you take several trips to the bathroom.
- Heartburn or acidity that is common in the other two trimesters too.
- Swollen ankles, joints or fingers. These are the side effects of your body changing rapidly.
- Tender or sensitive breasts that may even discharge the milky liquid already.
- Insomnia which may be either because of the anxiety or the hormonal changes, as well as the growing belly causing discomfort.
- Haemorrhoids, i.e. the swollen veins near the anus or in the lower rectum area.
When stepping into the third trimester, your baby may already have grown large. The foetal weight gain in the third trimester may vary from around two and a half pounds and sixteen inches long in the 28th week of pregnancy to around six to nine pounds and nineteen to twenty-two inches long by week 40.
This change may baffle you, but this is how a baby grows through the entire pregnancy period. Read on to see the stages of foetal development in the third trimester.
- Bones: When you enter the 32nd week of your pregnancy, by then the bones of your baby may get fully developed. The cartilage of the foetus fully transforms into bones, and the calcium required to develop healthy bones comes from your calcium-rich diet.
- Hair, Skin, and the Nails: When the 32nd week of your pregnancy starts, the baby’s skin may also develop fully, including hair growth and nail formation.
- Digestive System: When you reach the last few weeks of your pregnancy, meconium, or the baby’s “first poop”, consisting of blood cells, vernix, and the lanugo will start to show up in the fully formed baby’s intestines.
- The Senses: The foetus’ touch sensibility may develop in the 29th or the 30th week of pregnancy. And, by week 31 your unborn may start showing response towards the known senses, i.e. the ability to see and perceive light, taste senses, hearing, and smell.
- Brain Development: The brain may also show noteworthy growth in the third trimester as the foetus may be able to even dream or regulate its own body temperature.
- Organs: By the 37th week of pregnancy, the organs of the baby are also completely developed.
- Head Position: By the 36th week, the head of the foetus should be facing downwards. And, if after an ultrasound, your doctor tells you that this is not the case, then he may do his best to change the positioning or may suggest you go through a caesarian section surgery.
The third trimester means a large belly and along with that size increase, a lot of other things may occur in your body irrespective of them being visible or not. The following section puts light on some of these body changes:
- Stomach Pains: The round ligaments which support the lower abdomen start stretching to the extent that you may feel sharp intolerable stomach pain. This stretching is due to the adaptability of the body for accommodating the growing baby. There is no way you can avoid this pain rather than being patient and tolerable towards the pain.
- Tiredness: In your third trimester of pregnancy, you have to carry your weight along with the increasing weight of the baby. This may become difficult to handle and may result in you being tired every now and then. This discomfort may also lead to difficulty in sleeping, but it is up to your wisdom on how to move forward in an organized manner. It is advised to eat well, keep yourself moving but in limits, and manage your sleep well.
- Braxton-Hicks Contractions: This is one body change that would continue until the real labour starts. This is stiffness or the “practice contractions” that you may feel frequently that may even fool you into thinking that it is time for the delivery.
- Stretch Marks: To accommodate the growing size of the baby, your body stretches to the extent that stretch marks start showing up. These stretch marks are a sign of the normal growth your baby may be going through. You could gently apply moisturiser to the stretch marks to help reduce its effect.
- Back Pain: When you carry the weight of your body and the baby’s, your back supports it. But this may result in sharp back pain. The back pain may also occur because of the high secretion of “relaxin”, the pregnancy hormone; your joints start to loosen up, and the grown abdomen may pull the centre of gravity of the body in the forward direction.
- Frequent Trips to the Bathroom: In your third trimester, even a single sneeze can make you pee in your pants. This is because the additional weight on the pelvic floor that makes it irresistible to control peeing.
- Milky Breasts: Your breasts may start secreting the milky substance, and this may be the body’s sign that you are soon going to be a mother.
The weight gain in the crucial period of the third trimester is rapid. This is the time when your baby gains maximum weight. According to research, a baby generally weighs from around 2 pounds in the 27th week to 4 pounds in the 32nd week. By the end of the pregnancy or more precisely the 40th week, the baby’s weight may vary from 6-10 pounds.
Apart from the baby’s weight, your body weight may also increase due to the presence of fluids, amniotic fluid, over-sized uterus, or even the more blood formation. This is the reason a doctor advises to stay fit during the first two trimesters so that the entire body weight in the third trimester becomes easy to bear. Staying active and moving is the key here if you want to be saved on extra kilos that you put on.
Exercises You Can Try
Pregnant women who prefer exercising during the 40 week period enjoy better overall health, controlled weight, and better mood. Low to medium intensity exercises have always been recommended by physicians but one should keep the safety factor in mind.

- Walking and Light Jogging: Walking is the best exercise for pregnant women since time immemorial. Just get your sports shoes on and start walking on smooth pavement. Also, do not brisk walk as this may leave you tired. You could also do slow jogging unless you have complexities or any other discomforts.
Swimming: If you have a swimming pool to go to, why not use it? You could either swim through the pool or even do easy and recommended aqua activities. One of these activities could be lap swimming which could help in providing relief from abdominal pains. Water could prove to be soothing to the body in many ways, but it is recommended to not exert pressure on your body.
- Yoga: This is one of the best exercises that can help you stay fit, release stress, and keep your mood elated. Yoga also prepares you for taking on the labour pains in a less painful manner. Preferring to meditate and do the yoga for about 20 minutes would be more than enough but repeating it twice a day would be highly beneficial.
- Body Weight Workouts: You could also try squats, wall push-up or planks when in the third trimester of your pregnancy. These exercises can build stamina and the strength you would need during your labour period. Avoid crunches or any kind of abs-oriented workout in the last three months of the pregnancy.
