Final answer:
During pregnancy, changes in uterine size and shape, weight gain, enlarged breasts, and increased blood volume are probable signs that can make an examiner suspect a woman is pregnant. Maternal feelings of fetal movement provide a definitive confirmation of pregnancy.
Step-by-step explanation:
During pregnancy, there are several probable signs that can indicate a woman is pregnant. These signs include changes in uterine size and shape, which occur as the uterus expands to accommodate the growing fetus. Other signs include changes that make the examiner suspect a woman is pregnant, such as weight gain, enlarged breasts, and increased blood volume. While these signs strongly suggest pregnancy, they are not definitive confirmation. Maternal feelings of fetal movement, on the other hand, can provide a definitive confirmation of pregnancy. Feeling the baby move is a significant milestone that often occurs around the second trimester.
