True or False

Moderate coffee and caffeine consumption during pregnancy (two to three cups per day) is generally not associated with pregnancy complications or miscarriages. However, high levels of coffee and caffeine consumption may bring an increased risk of miscarriage.

The use of ultrasound during pregnancy has not been shown to harm the mother or the fetus. Ultrasound is a radiation-free procedure and is considered safe. Prolonged use of ultrasound with blood flow demonstration in the first trimester may theoretically cause tissue heating and is not recommended. However, ultrasound is typically used sparingly and only when necessary, following the principle of As Low As Reasonably Achievable (ALARA).

Moderate physical activity is beneficial for all women, whether or not they engaged in exercise prior to pregnancy. Engaging in physical activity does not increase the risk of premature birth. Rest and lack of physical activity do not prevent premature birth, even in individuals considered to be at high risk.

When it comes to premature birth, every day spent in the womb is valuable for the fetus's development and improves likelihood of a healthy outcome. Therefore, giving birth in the eighth month is preferable to giving birth in the seventh month.

Numerous studies have shown that early administration of an epidural during labor does not delay the progress of labor. If a woman is experiencing pain at the beginning of labor, even if the cervix is not significantly dilated, receiving an epidural does not affect the duration of labor.
