| Pregnancy Symptoms: Missed Menstruation
A delayed or missed menstruation is the most common pregnancy symptom leading a woman to test for pregnancy. When you become pregnant, your next period should be missed. Many women can bleed while they are pregnant, but typically the bleeding will be shorter or lighter than a normal period. This symptom is commonly explained by other reasons. If you have been sexually active and have missed a period, it is recommended that you take a test.
'13% of young men have chlamydia'
Thirteen per cent of men aged 20 to 24 are infected with chlamydia, early data from a screening programme has shown. Figures presented at the Health Protection Agency's annual conference show more than 180,000 young people have been screened since 2003. Screening, for under 25s across England, is available in a range of locations including youth clubs. The HPA data also showed 12% of young women aged 16 to 19 were infected with chlamydia, which can damage fertility. .
Simple blood test devised to predict pre-eclampsia
London, Sept 7: A simple blood test could predict a potentially fatal pregnancy complication up to three months before symptoms occur, researchers report. Women who go on to develop pre-eclampsia have high levels of two key proteins in their blood, the study found. The proteins, which disrupt blood vessel formation, also suggest potential targets for treatment. Pre-eclampsia is little understood and a dangerous complication occurring in up to 5 percent of pregnancies. It is the leading cause of premature delivery worldwide. The condition often strikes without warning, causing the womans blood pressure to spike and predispose her to developing blood clots. Some women go on to suffer convulsions and even death. For this reason, doctors may have to deliver her baby immediately, even if many weeks remain before its due date.
