Symptoms usually include one or more of the following: orthopnea (difficulty breathing while lying flat), dyspnea (shortness of breath) on exertion, pitting edema (swelling), cough, frequent night-time urination, excessive weight gain during the last month of pregnancy (1-2+ kg/week; two to four or more pounds per week), palpitations (sensation of racing heart-rate, skipping beats, long pauses ...
Menopause typically occurs between 44 and 58 years of age. [8] DNA testing is rarely carried out to confirm claims of maternity at advanced ages, but in one large study, among 12,549 African and Middle Eastern immigrant mothers, confirmed by DNA testing, only two mothers were found to be older than fifty; the oldest mother being 52.1 years at conception (and the youngest mother 10.7 years old).
A study found that CTG monitoring didn't significantly improve or worsen the outcome, in terms of preventable child death, post birth mortality, of pregnancy for high risk mothers. But the evidence examined in the study is quite old and there have been significant changes in medical care since then.
The study is based on the link between routinely-collected data (e.g. from the UK National Health Service and the Department for Education) and the results from POP study in order to determine which pregnancy parameters could predict a high risk of health or developmental problems. Using the existing and follow-up data collected during the POP ...
Gestational age at birth is on average shortened by various pregnancy aspects: twin pregnancy, prelabor rupture of (fetal) membranes, pre-eclampsia, eclampsia, intrauterine growth restriction. [29] The ratio between fetal growth rate and uterine size (reflecting uterine distension) is suspected to partially determine the pregnancy length.
According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
A qualitative study on couples in the United States who used in-vitro fertilization to conceive their first child when the woman was aged 40 or older at the time of delivery found that 72% of the women and 57% of the men believed that they had enhanced emotional preparedness for parenting which benefitted both their children and themselves.

Over 80% of pregnant women are regularly prescribed therapies that are untested in pregnant populations. [1] A study of medications approved by the FDA from 1980 to 2010 showed that 91% of medications for adults lacked data about the safety and efficacy for pregnant women, or determinations of risk to the fetus.
