Pregnancy can be detected either by using pregnancy tests, or by the woman herself noticing a number of symptoms including a missed menstrual period, increased basal body temperature, fatigue, nausea, and increased frequency of urination.
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 h CG (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.
Pregnancy requires different nutritional considerations than a person would have in a non-pregnant state, due to increased energy and specific micronutrient requirements.
Certain vitamins such as Vitamin B9, also known as folic acid, can help decrease the risk of certain defects, while other nutrients such as DHA omega-3 that is necessary for proper brain and retinal development cannot be produced efficiently by infants, and can only be obtained through the placenta during pregnancy, or in breast milk after birth.
Patient Platform Limited has used all reasonable care in compiling the information but make no warranty as to its accuracy.Alternatively, the due date can also be estimated based on a person's last menstrual period.While the due date can be estimated, the actual length of a pregnancy depends on various factors including age, length of previous pregnancies, and weight of the mother at birth.There are many other micronutrients that aid proper fetal development, and there exist myriad sources of information on what pregnant women should or shouldn't eat or do.All of the information can be different to sift through and can vary from person to person.
