Side Abdominal Pain During Pregnancy: What to Know - Obstetrics and Gynecology

Sometimes there is pain on the side of the abdomen?


Hello Doctor, I would like to ask you a question.
Since I became pregnant (currently over 4 months), I sometimes experience pain on the sides of my abdomen.
However, it doesn't last long, usually about a minute, and it mostly occurs when I turn over in my sleep.
Will this affect the baby? Sometimes when I sleep on my side, the baby kicks quite hard.
Am I possibly pressing on the baby? This often disrupts my sleep.
Thank you very much for your help!

More Info


During pregnancy, experiencing side abdominal pain can be a common concern for many expectant mothers. It is important to understand the nature of this pain and its implications for both the mother and the baby. In your case, since you are currently four months pregnant and experiencing intermittent side pain, particularly when turning in bed, it is essential to consider several factors.

Firstly, the pain you describe may be related to the stretching of the ligaments that support the uterus as it grows. This is known as round ligament pain, which is quite common during pregnancy, especially in the second trimester. The round ligaments stretch and can cause sharp pain on one or both sides of the abdomen, particularly with movements such as rolling over in bed or changing positions. This type of pain is usually brief and resolves quickly, as you have noted.

In terms of whether this pain could affect your baby, the good news is that occasional, mild side pain that resolves quickly is generally not harmful to the fetus. The baby is well-protected within the amniotic sac and the uterus, and the discomfort you feel is unlikely to cause any direct harm. However, if the pain becomes severe, persistent, or is accompanied by other concerning symptoms such as bleeding, fever, or significant changes in fetal movement, it is crucial to seek medical attention promptly.

Regarding your concern about the baby kicking when you are side-sleeping, it is normal for babies to be active, especially as they grow and develop. The kicks you feel are a sign of the baby’s movement and health. It is unlikely that your sleeping position is causing any harm to the baby. However, if you are uncomfortable, you might consider adjusting your sleeping position or using pillows for support to alleviate any pressure on your abdomen.

It is also worth noting that sleep disturbances during pregnancy are common due to physical discomfort, hormonal changes, and anxiety about the upcoming arrival of the baby. If you find that your sleep is significantly affected, it may be beneficial to discuss this with your healthcare provider, who can offer strategies to improve your sleep quality.

In summary, while side abdominal pain during pregnancy can be concerning, it is often a normal part of the body adjusting to the changes of pregnancy. As long as the pain is mild, brief, and not accompanied by alarming symptoms, it is unlikely to impact your baby negatively. Always feel empowered to reach out to your healthcare provider with any concerns, as they can provide personalized advice and reassurance based on your specific situation. Regular prenatal check-ups are also essential for monitoring both your health and the baby's development throughout your pregnancy.
