Pregnant and back pain

Back pain is common during pregnancy. Almost every pregnant woman experiences it, especially in the second half of pregnancy. A different position is often the cause, but sometimes also a bladder infection. Early in pregnancy, back pain can be caused by a miscarriage, implantation or EUG.

Pregnancy ailments

Being pregnant is a dream come true for most women, but it also brings with it the well-known pregnancy ailments. These are ailments and complaints that arise from pregnancy. Well-known ailments are nausea, especially in the morning. But also having to urinate more often, feeling bloated, blood loss and sometimes back pain are also part of it. Is back pain actually part of pregnancy? Sometimes yes, but sometimes back pain is also caused by something that arose during pregnancy.

Back pain due to implantation

When the egg is fertilized, it is transported to the uterus. During this journey the egg cell is already dividing, this process continues quickly. Once the egg has arrived in the uterus, it settles in the uterine wall. This implantation may be accompanied by blood loss. Some women clearly feel the implantation as some abdominal cramps or pain in the lower back. This pain does not last more than two days.

Ectopic pregnancy or EUG

Sometimes the egg does not implant in the uterus, but in the fallopian tube, ovary, cervix or abdominal cavity. This can happen when the egg gets stuck there due to a blockage. The egg cannot go any further and will continue to grow in, for example, the fallopian tube. This is not a problem in the beginning, but as the egg continues to divide, it grows extremely quickly and eventually there will be a shortage of space in the fallopian tube. A dangerous situation, because the fallopian tube can rupture. An ectopic pregnancy must be terminated immediately to limit damage. No fetus could survive outside the womb, no matter where it is located. Only the uterus is suitable for raising a fetus.
An ectopic pregnancy cannot be recognized at first. The pregnancy test is positive and all pregnancy ailments such as nausea are present. Later, bleeding, abdominal pain and dizziness may occur. When bleeding occurs in the abdominal cavity, the blood irritates certain nerves, causing pain in the shoulder or back. The pain is often felt on one side. Acute internal bleeding can be fatal, which is why an ectopic pregnancy must be detected as soon as possible.

A miscarriage also causes back pain

A miscarriage causes blood loss and abdominal cramps. These abdominal cramps can also radiate to the back. This pain is caused by the contraction of the uterus. A miscarriage is most common during the first three months of pregnancy, often noticeable from four weeks of pregnancy. This is usually caused by a predisposition error or sometimes an abnormality in the mother. If the pain and bleeding are severe and persist for a long time (longer than one week), it is advisable to visit the midwife or doctor.

Becoming heavier in the abdomen

During the second and third trimesters of pregnancy, the belly grows visibly and becomes heavier. If you were to continue walking upright, you would tip forward under the weight of your abdomen. You will automatically arch your back slightly to compensate for the weight. This can cause back problems, especially if the back is very concave and little rest is taken in between. The complaints consist of pain in the lower back or the middle of the back. Pain in the upper back is often caused by a tense position such as raising the shoulders. Pelvic instability can also develop. Pelvic pain is felt that can radiate to the back. These complaints can worsen, especially when standing for a long time.


Pregnant women have a greater chance of getting a bladder infection. You then have to urinate more often and there is a burning or painful feeling during and immediately after urination. Sometimes there is also back pain caused by the bladder infection. Not every woman has the same complaints. Back pain that cannot be explained may therefore indicate a bladder infection. A urine test can determine this with certainty. A bladder infection is treated with a course of antibiotics that is safe for the baby.

Crooked vertebra

Abnormalities of the spine or a crooked pelvis emerge much earlier during pregnancy. Not everyone has a perfectly straight back. If the spine is slightly crooked, this can cause back pain, especially during pregnancy. A physiotherapist can help with the correct posture during, but also after, pregnancy. If back problems persist after pregnancy, it is useful to have it looked at.
