Bloody show or show is the passage of a small amount of blood or blood-tinged mucus through the vagina near the end of pregnancy.It is caused by thinning and dilation of the cervix, leading to detachment of the cervical mucus plug that seals the cervix during pregnancy and tearing of small cervical blood vessels, [1] and is one of the signs that labor may be imminent.

Many symptoms and discomforts of pregnancy, such as nausea and tender breasts, appear in the first trimester. [56] During the second trimester, most women feel more energized and put on weight as the symptoms of morning sickness subside. They begin to feel regular fetal movements, which can become strong and even disruptive. [citation needed]
The first ten weeks of gestational age is the period of embryogenesis and together with the first three weeks of prenatal development make up the first trimester of pregnancy. From the 10th week of gestation (8th week of development), the developing embryo is called a fetus.
The fetus is considered full-term at the end of the 39th week of gestational age. It may be 48 to 53 cm (19 to 21 in) in length. The lanugo is gone except on the upper arms and shoulders. Fingernails extend beyond fingertips. Small breast buds are present on both sexes. Head hair is now coarse and thickest.
In the first trimester, a standard ultrasound examination typically includes: [12] Gestational sac size, location, and number; Identification of the embryo and/or yolk sac; Measurement of fetal length (known as the crown-rump length) Fetal number, including number of amnionic sacs and chorionic sacs for multiple gestations; Embryonic/fetal ...
Small breast buds are present in both sexes. Head hair becomes coarse and thicker. Birth is imminent and occurs around the 38th week after fertilization. The fetus is considered full-term between weeks 37 and 40 when it is sufficiently developed for life outside the uterus. [14] [15] It may be 48 to 53 cm (19 to 21 in) in length when born.

The hypothesis that human fetuses are capable of perceiving pain during the first trimester has little evidence, although fetuses at 14 weeks may respond to touch. [ 7 ] [ additional citation(s) needed ] A multidisciplinary systematic review from 2005 found limited evidence that thalamocortical pathways begin to function "around 29 to 30 weeks ...
