In the first weeks of pregnancy, a woman's body begins to change to accommodate the
growing embryo. For the mom, that means a wide range of new sensations, some more
pleasant than others. Some pregnant women experience only a few of these symptoms, while
others experience all.
* Amenorrhea, or absence of menstrual period. When you become pregnant, the rising
hormone levels prevent you from shedding the uterine lining at the time you expect your
period. You can also miss your period if not pregnant. Other possible causes: weight gain or
loss, hormonal problems, tension, stress, breastfeeding, and discontinuing the pills or
* Morning sickness is nausea and vomiting, usually in the morning, but sometimes all day. It is
thought to be caused by the high level of the hormone human chorionic gonadotropin (HCG)
in the blood, rapid stretching of the uterine muscles, excess acid in the stomach and an
enhanced sense of smell. Morning sickness usually starts two to eight weeks after
conception. Other possible causes of nausea include food poisoning, tension, infection,
gallbladder disease and other diseases.
* Breasts tender and swollen. The breasts of a pregnant woman change as levels of the
hormones estrogen and progesterone rise in the first weeks of pregnancy. Some women even
notice milk leaking from their breasts, although this usually occurs later in pregnancy. The
tenderness usually begins a few days after conception. Other possible causes of breast
tenderness include birth control pills, beginning of your period and fibrocystic breast condition.
* Darkening of the areolas, the skin is around the nipples. The bumps on areolas (called
Montgomery nodules) may be more prominent. These changes happen gradually during the
first weeks of pregnancy, as your breasts prepare to produce milk. Other possible causes
include hormonal imbalance, prior pregnancy, tanning and physical changes of puberty.

during the first quarter. Other possible causes include poor diet, stress and the beginning of

corpoorales flow and pressure of growing uterus go to the bathroom more often. Usually, they
start at six to eight weeks after conception. Other possible causes of frequent urination
include urinary tract infection, diuretics, tension, diabetes and drinking excess fluid.
* Fatigue. During the first months of pregnancy, your body is building your baby's placenta,
the organ that will provide nourishment over the next nine months. That takes energy and,
together with high levels of the hormone progesterone, very tired mothers. As we approach
the end of the first trimester, women often begin to feel less fatigued. Other possible causes
of fatigue include tension, stress, depression, poor diet, lack of exercise, sleep, and sleep
* Bleeding. About a quarter of women with normal pregnancies will have some bleeding pink
or brown, sometimes accompanied by stomach cramps. While the majority of women with
spotting or bleeding have normal pregnancies, bleeding can also be a sign of spontaneous
abortion or ectopic pregnancy, a medical problem which may be a potential threat to life. If
you have bleeding, contact your health care provider to have an ultrasound and make sure
that your pregnancy is progressing normally. Other possible causes of spotting include the
beginning of your period or bleeding from the discontinuation of the pill.
