Many women have no clue they are pregnant until they take a home pregnancy test after a missed period. However, women who are trying to conceive will have some symptoms in the first week of a pregnancy that can help them recognize their condition. Symptoms at one week will generally be mild and may be attributed to something else. Prenatal care is very important to the health of a baby and mother so contacting an OB/GYN as soon as a pregnancy is confirmed is very important.
Ovaries
The ovaries are a key player in a women's reproductive cycle and being pregnant causes changes in them. Some women report a twinge or cramp when they release an egg and this can occur on one or both sides. Once that egg has been fertilized and pregnancy occurs, some women will experience light bleeding around the time their period would have arrived. This is the egg implanting in the uterus and the bleeding is generally very light and only lasts for a day or two.
Temperature
Women trying to conceive often keep track of their basal body temperature, which can indicate ovulation. An elevation in temperature means a women is in her most fertile time of the month and once pregnant this temperature will stay raised throughout the pregnancy. This is due to the increase in progesterone in the body.
Body
In general, no two pregnancies are the same, but there are some common symptoms that women report early on in a pregnancy. In the first week, a women will feel unusually tired due to the work the body is doing to sustain the body's changes. Additionally, due to the increase in fluid in the body, women may experience frequent urination. Hormones can cause bloating early on, but this is not the same thing as beginning to show, which occurs later in the pregnancy. Finally, many women report nausea and an increased sensitivity to smells.
