Causes of tonus
Uterine tone can occur on different termspregnancy. This can happen both at the beginning of pregnancy, and in the middle, and at the end. The emerging tone of the uterus during pregnancy has many causes, both functional and hormonal. The reason for his appearance in the early stages of pregnancy is, more often than not, a violation of the hormonal background in the future mother. As a result, the body reduces the production of progesterone, which is the main hormone of pregnancy and responsible for its successful course. When determining the normal development of the embryo with the help of ultrasound, doctors prescribe the use of antispasmodics, progesterone preparations and reduced exercise stresses for the preservation of pregnancy. Progesterone helps to reduce the excitability of the uterus, protects the fetus from penetration of infections and helps the placenta to develop properly, and also, so that the pregnant woman is relaxed and calm, calmingly acts on the nervous system. It is usually taken up to 16-18 weeks and ends when the placenta is finally formed. The tone of the uterus during pregnancy at 16-17 weeks is due to the fact that the uterus greatly increases in size and presses on the bladder, neck, and other organs. There are also pains in the lower back and back. In this case, it is necessary to wear an antenatal bandage that helps to relieve the load from the spine and distribute it evenly throughout the abdomen. If the tone of the uterus during pregnancy, starting at 34-35 weeks, appears sporadically, it may be harbingers of labor. This is a kind of training the body before the forthcoming birth. 
Diagnosis and prevention
There are several ways to diagnosehypertension of the uterus. Often it can be seen even with a simple gynecological examination. But the most common method of diagnosis is ultrasound. It shows the state of the musculature of the uterus. Ultrasound can show such pathologies as tonic uterus on the front or back wall of 1 or 2 degrees. Elevated tone of the uterus can be measured with special instruments, but they are not very common, since the diagnosis of this problem is not very difficult. To determine the cause of the appearance of a tone is much more difficult. Prevention of hypertension is very simple. Most importantly, you need to avoid unnecessary stress and exercise. It is also necessary to eat right and observe the regime of the day: about the same time, go to bed and get up. At this time, a healthy dream and a full rest are very important. Separately, it is necessary to mention various harmful habits, such as smoking and drinking alcohol, which can also be the cause of the appearance of tonus. As you know, both cause increased uterus tone, and other pathologies, even more unpleasant. Therefore, it is better to give up tobacco and alcohol before you become pregnant.

And the excitement will only worsen the condition of the pregnant woman.

If the signs of the tone of the uterus do not pass at rest, unusual discharge and pain appear in the lower abdomen, pulls the lower back, then you must necessarily show yourself to the doctor. It is always necessary to pay attention to the unusual behavior of the child, if he unusually quieted down, or, on the contrary, is too restless. If irregular cramping pains appear during tonus, you need to see the doctor so that the threat of termination of pregnancy is excluded. The doctor will examine you, if necessary, make an ultrasound, listen to the heartbeat of the fetus and prescribe medication that will relax the musculature of the uterus. If this examination shows a threat of miscarriage and you are offered to go to the hospital, you do not have to give it up, because the health and life of the unborn child depends on it, since the blood vessels of the placenta are squeezed by hypertension of the uterus and cause the baby to suffer from lack of oxygen and nutrients in utero. Along with painful and prolonged contractions of the uterus in the second trimester, ultrasound can show a tendency to the opening of the cervix and its shortening. To remove the tone and stay pregnant in this case, a strict bed rest and treatment in the hospital. With the development of tone in the 3rd trimester, due to the preparation of the cervix for labor and changes in the hormonal background, contractions can become generic.
