Low back pain in early pregnancy does not necessarily lead to miscarriage, if there is a miscarriage there will be low back pain. It is normal to have low back pain in early pregnancy because the hormonal changes in the body after pregnancy will easily cause pelvic congestion, which will also increase tissue edema and lead to low back pain, the increase in the size of the uterus after pregnancy will press on the lower back and cause pain, calcium deficiency after pregnancy will also cause low back discomfort, and lumbar muscle strain will aggravate the strain after pregnancy and lead to low back pain and low back pain. If there is no vaginal bleeding due to simple back pain, there is no need to worry, just pay attention to bed rest and do regular maternity checkups. If the strain is caused by acupuncture and massage, if the lumbar pain is accompanied by bleeding, it is considered to be miscarriage, it is better to do ultrasound to check the fetal development, if the fetal development is normal, it is necessary to use progesterone to keep the fetus in time.
