Epub Mar Pregnancy tests involve detection of hormones that serve as biomarkers for pregnancy and include clinical blood or urine tests that can detect pregnancy from six to eight days after fertilization.
While clinical blood tests are more accurate, and can detect exact amounts of the hormone hCG which is only present during pregnancy earlier and in smaller quantities, they take more time to evaluate and are more expensive than home pregnancy urine tests.
It is also possible to get a clinical urine test, but these are not necessarily more accurate than a home pregnancy test, and can potentially be more costly.

It affects many cts of fetal development such as the weight of the baby, the placenta, extra circulatory fluid, and its fat and protein stores.
Weight management merits consideration because insufficient or excessive weight gain can have negative effects for both mother and fetus including the need for cesarean section C-section and gestational hypertension. While the values vary between women, the Institute of Medicine recommends an overall pregnancy weight gain of pounds for women who are considered "normal" weight BMI Studies indicate that aerobic exercise during pregnancy helps to improve or maintain physical fitness as well as possibly decreasing the risk of C-section.
Although it varies between women, regular aerobic and strength-conditioning exercise are often recommended for pregnant women, and women who exercised regularly before pregnancy, who have uncomplicated pregnancies, should be able to continue high intensity exercise programs. Nevertheless, caution is advised, and a pregnant woman should consult their doctor if any of the following symptoms present: vaginal bleeding, shortness of breath, dizziness, headache, calf pain or swelling, amniotic fluid leakage, decreased fetal movement, preterm labor, muscle weakness, or chest pain.
