Doppler fetal monitor. In later stages of pregnancy, a simple Doppler fetal monitor can be used to quantify the fetal heart rate. A fetal heartbeat can be detected at around 17 to 20 weeks of gestation when the chambers of the heart have become sufficiently developed. [20]
Gestational age: 8 weeks and 0 days until 8 weeks and 6 days old. 57–63 days from last menstruation. Embryonic age: Week nr 7. 6 weeks old. 43–49 days from fertilization. The embryo measures 18 mm (3 ⁄ 4 in) in length. Fetal heart tone (the sound of the heart beat) can be heard using doppler. Nipples and hair follicles begin to form.
Pregnant women fall at a similar rate (27%) to women over age of 70 years (28%). Most of the falls (64%) occur during the second trimester. Additionally, two-thirds of falls are associated with walking on slippery floors, rushing, or carrying an object. [38] The root causes for these falls are not well known.

Stretch marks; Breast tenderness is common during the first trimester, [14] and is more common in women who are pregnant at a young age. [31]
The growth rate of an embryo and infant can be reflected as the weight per gestational age, and is often given as the weight put in relation to what would be expected by the gestational age.

Understanding Heart Rate and Age-Related Changes. Heart rate is the rate or speed at which your heart beats, and it’s determined by counting the number of beats per minute while you’re at rest ...
A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations. "Reactive" is defined as the presence of two or more fetal heart rate accelerations within a 20-minute period. Each ...
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
