[1] [2] It is medically defined as a separate entity from a chorionic hematoma. [3] Identification of a chorionic bump in early first trimester pregnancy represents a significant risk factor for pregnancy loss, given a live birth rate of less than 50%. [4] The incidence rate for chorionic bump is estimated to be between 1.5 and 7 per 1000 ...
Quickening indicates the start of fetal movements, usually felt 14–26 weeks after conception, or between the fourth and sixth month. [5] [6] A woman pregnant for the first time (i.e., a primigravida woman) typically feels fetal movements at about 20–21 weeks, whereas a woman who has given birth at least once will typically feel movements ...
The earliest fetal response to a sound stimulus has been observed at 16 weeks' gestational age, while the auditory system is fully functional at 25–29 weeks' gestation. [4] At 33–41 weeks' gestation, the fetus is able to distinguish its mother's voice from others.
Ages are given as age from fertilization rather than as gestational age. Some sources contend that there is no voluntary movement until after birth. [3] Other sources say that purposive movement begins months earlier. [4] 3D ultrasound has been used to create motion pictures of fetal movement, which are called "4D ultrasound". [5]
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).

Vibroacoustic stimulation (VAS), sometimes referred to as fetal vibroacoustic stimulation or fetal acoustic stimulation test (FAST), is the application of a vibratory sound stimulus to the abdomen of a pregnant woman to induce FHR (fetal heart rate) accelerations.
