| Different Pregnancy Symptoms
Pregnancy symptoms differ from woman to woman and pregnancy to pregnancy; however, one of the most significant pregnancy symptoms is a delayed or missed menstrual cycle. Understanding pregnancy symptoms is important because each symptom may be related to something other than pregnancy. Some women experience pregnancy symptoms within a week of conception. For other women, symptoms may develop over a few weeks or may not be present at all. Below is a listing of some of the most common pregnancy symptoms.
Early Signs Of Pregnancy - Sign 3
If you're like most women, morning sickness won't hit until about a month after conception. (A lucky few escape it altogether.) But some women do start to feel queasy a bit earlier. And not just in the morning, either — pregnancy-related nausea and vomiting can be a problem morning, noon, or night.
About half of women with nausea feel complete relief by the beginning of the second trimester. For most others it takes another month or so for the queasiness to ease up.
Researchers link placental proteins to preeclampsia
Two proteins secreted by the placenta may be responsible for virtually all cases of preeclampsia, a severe complication of pregnancy that can be fatal to mother or baby, researchers reported today. Abnormally high levels of the proteins could be used to predict the development of the disorder weeks before symptoms occur, experts said, and the findings suggest new ways to treat the problem. A World Health Organization team is beginning to organize a test of the proteins' predictive value among pregnant women in the Third World, and Fremont-based biotech company Scios Inc. is looking for funding to test a potential treatment. "This finding appears to be an important step in developing a cure for preeclampsia," said Dr. Elias Zerhouni, director of the National Institutes of Health.
