Early Signs Of Pregnancy: Presumptive And Probable Signs

Several changes that women experience are used to diagnose pregnancy. These include presumptive or subjective signs, probable or objective signs, and positive or diagnostic signs.

Early signs of pregnancy are those subjective changes that women herself experiences. they do not confirm a pregnancy because other factors also may cause them. In conjunction with other signs, however, they can be diagnostic.

the first sign that women generally experience is amenorrhea. In a women with regular cycles, one or two missed menstrual periods suggest pregnancy. Another presumptive sign is morning sickness, nausea and vomiting that often occurs in the morning and fades during the day. Women actually may experience variations in nausea and vomiting, however, which range from distaste of certain foods or odors, vomiting throughout the day, or vomiting at night. Nausea and vomiting usually appear 6 weeks after the first day of the last menstrual period and last for approximately 6 to 12 weeks, ending with the beginning of the second trimester. Occasionally, nausea and vomiting are prolonged beyond this time frame.

Excessive fatigue may begin within a few weeks after the first day of the last menstrual period and may be present during the entire first trimester. Women in the first trimester also may experience urinary frequency, which develops as the enlarging uterus exerts pressure on the bladder. This will diminish as the uterus rises in the abdomen, returning again near the end of pregnancy.

The women may notice breast changes, including enlargement, tingling sensations and tenderness, during the first few weeks of pregnancy. Pigmentation of nipples are areolae also may change, along with increased visibility of the veins, especially in those women with fair skin, occurring after the second month.

The woman may experience quickening, the first perception of fetal movement. Clients often describe quickening as a fluttering in the abdomen that increases in frequency and duration until the movements become perceptible as distinct fetal movements that will continue throughout the pregnancy. Quickening usually occurs between 16 and 20 weeks gestation.

Probable signs of pregnancy are those objective changes assessed by the examiner to identify the stages of pregnancy. Even though they are more diagnostic than presumptive signs, they are not a definitive diagnosis- again, probable signs may result from other factors.

Changes to the uterus and vagina are the only probable signs detectable in the first trimester. They include softening of the cervix; the dark violet coloration of the cervix, vagina and vulva, and the softening of the lower part of the uterus between the cervix and the body. In creased circulation to the area and circulating estrogen cause these changes, which usually are evident by 6 to 8 weeks gestation.

Progressive uterine enlargement, especially accompanied by continuing amenorrhea, is usually evidence of pregnancy. This enlargement may be more pronounced in multigravidas, whose abdominal musculature has lost some tone from previous pregnancies. The fundus of the uterus is palpable just above the symphysis is pubis at 10 to 12 weeks gestation and at the level of the umbilicus at 20 to 22 weeks. Abdominal palpation may reveal Braxton-HIcks contractions at approximately the 28th week.
