3rd trimester of your Pregnancy



3rd trimester of your Pregnancy

3rd trimester Ultrasound

Takes place between 28 and 32 weeks, and evaluates the foetal growth and well-being. Estimates foetal weight, determines the foetal position, placenta location, volume of the amniotic fluid and cervix size.


This is an exam that evaluates foetal well-being by interpreting variations in the foetal heart rate, associating it with maternal contractions or foetal movement. Lasts approximately 20 to 30 minutes and it is advisable to eat a meal or something sweet before. What does it entail? Two elastic straps are adjusted around the belly and two transducers are applied. One to capture foetal heart movements and the other to capture uterine contractions.

Sexual intercourse

The couple’s sex life should be maintained without restrictions (except in case of contraindications), adapting positions to the mother’s comfort. At the end of the pregnancy, sexual activity may be advised to accelerate labour.

Discomfort during pregnancy

If you suffer from...

What to do?

2. Urinate frequently, carry out pelvic exercises several times a day. Consult your physician if the problem persists after labour.

3. Move slowly and avoid major exertion, sit up straight, sleep with one or two extra pillows to rest in a semi-reclined position.

Warning signs

• Haemorrhages;

• Persistent abdominal pain;

• Fever;

• Feeling little or no baby movement;

• Repeated contractions before due date which do not subside with rest;

• Loss of amniotic fluid;

• Vaginal discharge with itching or burning;

• Pain or burning during urination;

• Persistent vomiting;

• Excessively swollen face and limbs in the morning;

• Strong or persistent headaches;

• Altered vision;

• Itching palms of the hands or soles of the feet

Labour signs

• Secretions with traces of blood: Similar to a gelatinous discharge, dark pink or with traces of bright blood. Loss of the mucus plug occurs when the cervix begins to dilate, indicating that the pregnancy is full-term

• Regular uterine contractions

• Ruptured membranes: You should go to the hospital if your waters break, even if contractions are irregular

• Cervix begins to dilate

When to go to the hospital

Contractions are rhythmic and progressively more regular and prolonged. When they occur every 10 minutes, you should make your way to the hospital calmly. False labour pains are irregular contractions that do not increase in intensity or frequency over time and diminish with rest.
