To determine the duration of pregnancy, doctors take into account presumptive and probable signs.
Possible ones include:
• changes in appetite, taste, smell,
• nausea and vomiting, drooling,
• weakness, malaise,
• irritability and tearfulness,
• dizziness and headaches,
• insomnia,
• deposition of subcutaneous fat layer,
• stretch marks on the stomach,
• skin pigmentation (on the face, along the white line of the abdomen, in the area of the nipples and external genitalia).
Such signs can be observed not only in pregnant women. But for a doctor they have diagnostic value, because some of them occur before objective signs of pregnancy.
Possible signs objectively confirm pregnancy: in women of childbearing age, menstruation suddenly stops, the mammary glands, uterus, and vaginal mucosa change. Let's look at them in a little more detail.
Changes in the chest.
The mammary glands enlarge. When pressed, a clear liquid is released from the nipples - colostrum.
Changes in internal organs.
At 1 month of pregnancy, the uterus enlarges to the size of a chicken egg. The cervix becomes drier. The mucous membrane of the vagina and cervix acquires a bluish tint and becomes more loose.
Pain.
During this period, the stomach may hurt as the uterus prepares to receive a fertilized egg, which moves towards it to gain a foothold in the cavity. On the anterior wall of the uterus there are round uterine ligaments, they begin to stretch, the uterus enlarges, and therefore the woman feels pain in the lower abdomen. This is not a threat of termination of pregnancy, but a variant of the norm.
Do you have periods in the first month of pregnancy?
Normally, a pregnant woman should not have menstruation. Some people experience spotting for several months or even throughout their pregnancy. This is a menstrual-like reaction, but not menstruation.
What does the stomach look like?
In the first month of pregnancy, a woman relies more on sensations: external manifestations are not yet bright enough or are completely absent. For example, in the early stages the belly does not increase. It begins to grow by 12-14 weeks, when the uterus rises to the level of the womb.
