In the early stages of pregnancy, as the embryo lays and develops in the body, the woman’s body environment will change accordingly and therefore may cause some uncomfortable reactions. The symptoms of early pregnancy usually include cessation of menstruation, breast swelling, nausea and vomiting, and frequent urination. However, it is important to remind pregnant women that not all vomiting is a symptom of early pregnancy. The following is to popularize what are the symptoms of early pregnancy. 1. Stopping menstruation This is the most commonly noticed sign of pregnancy in general. As long as women who are generally of childbearing age and have normal menstruation exceed the normal period for two weeks after sexual intercourse, it is possible that they are pregnant, which is the earliest sign of pregnancy, and the longer the period expires, the greater the possibility of pregnancy. However, women’s reproductive functions are very sensitive, so it is not true that the absence of menstruation means pregnancy. There are many reasons for the absence of menstruation, which may be due to poor ovarian function, irregular hormonal secretion, busy work schedule, exam tension, etc. Late menstruation can be caused by mental stress or changes in the environment. Women who usually have bad periods should not be particularly nervous if they are late for their periods. Therefore, it is best to be diagnosed by a physician to be on the safest side. Women who have a normal married life should first consider whether they are pregnant once they are late for their period, but it is also important to observe the changes in their own physiology in addition to the absence of a period. This is especially true if you are already pregnant and do not know it, mistaking bleeding for a menstrual period. In the early stages of pregnancy, menstrual-like bleeding, which resembles menstruation but is not menstrual, may occur again. Although menstrual bleeding is a small amount of light-colored bleeding, it is sometimes a precursor to miscarriage and should be diagnosed by a doctor as soon as possible. 2, nausea and vomiting Most pregnant women in the first trimester will inevitably experience varying degrees of nausea and vomiting, which the elderly say is the “puerperium” and often occurs in the morning. Treatment can be food therapy, that is, to avoid greasy and fried food. For example, eating a few soda crackers before getting out of bed in the morning, and drinking fruit juice can also improve symptoms. If it is still very serious, you can take “antiemetic” and “vitamin B6” to improve; if it is serious enough to cause hypoglycemia, dehydration and liver function abnormalities, you need to be hospitalized. 3.Frequent urination and the feeling of bowel movement After pregnancy, because the uterus gradually becomes larger, pressing forward to the bladder, the content of the bladder becomes smaller and smaller, so when the urine accumulates to a certain level, there will be a sense of urination, so that often run to the bathroom, but only a trickle of water, unlike the previous surge. The same thing happens in the colon. When the colon is stimulated, there is a feeling of urgency to pass stool. After 3 months, the pelvic cavity will not be able to accommodate the enlarged uterus, and the uterus will rise into the abdominal cavity, so that the pressure on the bladder and large intestine will gradually disappear, and the frequent urination and the feeling of bowel movement will be relieved at the same time. 4.Lower abdominal pain Lower abdominal pain is not only considered pathological, such as miscarriage, cystitis, gastroenteritis, uterine fibroids, etc. The abdominal pain on both sides may be due to the enlarged uterus, which pulls the breech belt that fixes the position of the uterus on both sides, and is especially likely to occur on the left side. It usually occurs after certain postures, such as sudden standing, bending, coughing and sneezing, and usually disappears after 2 to 3 weeks. 5.Back pain Most of the back pain caused by pregnancy is due to the change of posture. As the uterus grows, the waist will involuntarily lean back in order to overcome the protruding abdomen, causing local muscle strain. In serious cases, you should consult an orthopedic surgeon to see if there is a possibility of disc protrusion. 6.Headache The headache caused by the change of blood flow in the brain due to the effect of hormones is the most common. However, sinusitis, poor eyesight, cold, lack of sleep, etc. are all possible causes. If the headache persists and the medication does not improve, it is advisable to consult a doctor to consider the possibility of brain tumor. 7. Changes in the breasts There may be breast development, enlarged nipples, visible veins under the skin of the breasts, deepening of the color of the nipples and areolas, prominent nipples, small nodules around the nipples, and even tingling, swelling and itching sensations in the breasts, and occasionally a small amount of milk may be squeezed out, all of which are caused by pregnancy. Due to the influence of progesterone, the breasts start to increase in size and become more sensitive after 4 to 6 weeks of pregnancy, and their total weight can increase to about 800 grams. The combined effect of this increase in weight and progesterone stretches the ligaments and fibrous tissues of the breasts, so they have a tendency to sag. It is important to choose a special corset to protect them. With the increase in blood volume, some pregnant women may also have blue blood vein reticulation on their breasts, which mostly disappears naturally after delivery.
