It is impossible to determine whether the back pain in late pregnancy is specifically about to be born. This is because in late pregnancy, due to the rapid development of the fetus, pregnant women are easily deficient in various nutrients and minerals, especially calcium, vitamins and iron. Once deficient, it will easily cause back pain and lumbago. When lumbago is accompanied by leg cramps and sciatica, besides taking calcium and vitamin B12 supplements, you should consult your doctor for help. For mild deficiency, dietary supplementation is recommended. In the later stages of pregnancy, as the fetus develops further and the fetus gradually enters the pelvis, it can also lead to symptoms such as back pain. On the other hand, it is also important to note that some pregnant women have contractions that manifest as regular back pain. Therefore, severe pain in the second trimester may be a symptom of labour. If the pain is unbearable, it is recommended to go to the hospital for examination.
