How long does it take for back pain to occur during pregnancy?

Pregnancy is a very difficult process for women, because during this period they not only have to endure many physical discomforts, but also have to face the phenomenon of their body shape changing. Many women will experience back pain during pregnancy, but the time when back pain occurs is different for each woman. Some women experience it in the early stages of pregnancy, while others experience it in the late stages of pregnancy. For a normal woman, how long does it take for back pain to occur?

1. Will I have back pain in the first few days of pregnancy?

It is normal to have back pain in the early stages of pregnancy and it is within the normal range. This is because, in the early stages of pregnancy, the joint ligaments relax due to the influence of hormones, the uterus enlarges, and compresses the pelvic tissues and nerves. As the abdomen enlarges, the body's center of gravity moves backwards, and in order to adapt to the balance of the body posture, the pregnant woman's waist protrudes forward, resulting in back pain.

The occurrence of back pain and other symptoms in the early stages of pregnancy is related to poor physical condition or excessive fatigue, and it is necessary to consider the possibility of threatened abortion. Occasional mild pain does not need to be treated, because as the fetus grows, the waist's ability to withstand it becomes greater and greater, so back pain is inevitable. But it is worth noting that if the pregnant woman feels severe abdominal pain, or finds that there is vaginal bleeding, be careful of ectopic pregnancy and check it out in time.

2. What is the cause of back pain in early pregnancy?

Most of the back pain caused by pregnancy is due to changes in posture. As pregnancy progresses, the uterus grows larger and the body's center of gravity gradually moves forward, forcing the pregnant woman's shoulders to move backward accordingly to maintain body balance. The neck is slightly bent to compensate for and maintain the upright head. As a result, the normal curvature of the spine increases, leading to lordosis, which causes local muscle pulling and the appearance of low back pain in early pregnancy. Therefore, the closer to full term, the more likely pregnant women are to experience neck, back and waist pain. The pain most complained by pregnant women is low back pain. Although the degree varies, almost everyone has feelings of pain.

At the same time, lower back pain in the early stages of pregnancy is caused by the fact that the fertilized egg gradually grows after implantation, which stimulates the uterus and sometimes causes uterine contractions. At this time, the hormone levels also change to a certain extent, so this is lower back pain caused by the stimulation of the uterus during pregnancy. If there is slight abdominal distension and pain, it may be related to pregnancy reaction.

It should be noted that the pathological cause of low back pain in early pregnancy may also be caused by ectopic pregnancy. Therefore, low back pain in early pregnancy, especially within 12 weeks of pregnancy, should not be easily ignored. In addition to abdominal pain, attention should be paid to observe whether there is any irregular vaginal bleeding, which is mostly spot-like, dark brown, small in amount, and not exceeding the menstrual volume. If a pregnant woman feels severe abdominal pain, or finds vaginal bleeding, she should be careful of ectopic pregnancy, so she can go to the hospital for an ultrasound examination if necessary.
