The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
Prenatal care in the United States is a health care preventive care protocol recommended to women with the goal to provide regular check-ups that allow obstetricians-gynecologists, family medicine physicians, or midwives to detect, treat and prevent potential health problems throughout the course of pregnancy while promoting healthy lifestyles that benefit both mother and child.

Transabdominal chorionic villus sampling is an alternative to amniocentesis if genetic diagnostic testing is to be performed in the first trimester between ten and 15 weeks' gestation. [3] It is important to note that prenatal genetic testing cannot identify all possible fetal genetic abnormalities or their outcomes. [ 5 ]
Photos of what pregnancy tissue from early abortions at 5 to 9 weeks actually looks like have gone viral.. The images, which were originally shared by MYA Network — a network of physicians who ...
Around weeks 11–13, nuchal translucency scan (NT) may be offered which can be combined with blood tests for PAPP-A and beta-hCG, two serum markers that correlate with chromosomal abnormalities, in what is called the First Trimester Combined Test. The results of the blood test are then combined with the NT ultrasound measurements, maternal age ...
If this is the case, the woman may be advised to have a more reliable screen such as cell-free fetal DNA screening or an invasive diagnostic test (such as chorionic villus sampling or amniocentesis). Screening for Down syndrome by a combination of maternal age and thickness of nuchal translucency in the fetus at 11–14 weeks of gestation was ...
Braxton Hicks contractions, also known as practice contractions or false labor, are sporadic uterine contractions that may start around six weeks into a pregnancy. [1] However, they are usually felt in the second or third trimester of pregnancy. [2]
When an echogenic intracardiac focus is identified in an otherwise normal second trimester fetus, a normal cell-free DNA test can be very reassuring and obviate the need for invasive testing. Amniocentesis is a test to check a baby's chromosomes. A small amount of amniotic fluid, which contains some fetal cells, is removed and tested.
