[24] 70% of pregnancies with a single episode of reduced fetal movements are uncomplicated. [ 24 ] [ 25 ] In the UK, the Royal College of Obstetricians and Gynaecologists say that if you think your baby has stopped moving or is moving less and you are over 28 weeks pregnant you should contact your midwife.
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [2] [1] [3] The term "non-reassuring fetal status" has largely replaced it. [4]
The risk of placental abruption can be reduced by maintaining a good diet including taking folate, regular sleep patterns and correction of pregnancy-induced hypertension. [citation needed] Use of aspirin before 16 weeks of pregnancy to prevent pre-eclampsia also appears effective at preventing placental abruption. [18]
Insufficient fetal growth can result in reduced amniotic fluid volume. When the fetus is not growing appropriately, it may have a reduced ability to produce urine, which is a significant contributor to amniotic fluid. [11] Amnion nodosum; failure of secretion by the cells of the amnion covering the placenta [citation needed]
A woman pregnant for the first time (nulliparous) typically feels fetal movements at about 21 weeks, whereas a woman who has given birth before will typically feel movements by 20 weeks. [13] By the end of the fifth month, the fetus is about 20 cm (8 in) long.
Progesterone also causes decreased motility of the ureters, which can lead to stasis of the urine and hence an increased risk of urinary tract infection. [6] Pregnancy alters the vaginal microbiota with a reduction in species/genus diversity. [34] Physiological hydronephrosis may appear from six weeks. [35]
At least three discrete body/limb movement in 30 minutes (episodes of active continuous movement considered a single movement. Less than three or two [3] movements US: Fetal muscle tone At least one [3] episode of active extension with return to flexion of fetal limb(s) or trunk, opening and closing of hand considered to be normal tone.
A baby's chances for survival increases 3 to 4 percentage points per day between 23 and 24 weeks of gestation, and about 2 to 3 percentage points per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [16]
