The mother’s beauty
According to a myth, girls steal away their mothers’ beauty. Of course, the truth of the matter is that morning sickness, changing hormone levels, and an expanding baby bumps leave many pregnant women exhausted. So, pregnant women aren’t always at the peak of their beauty regardless of the sex of the future baby.
Nausea (and/or vomiting) during pregnancy can occur at any time of day due to changes in your hormones. For the most women, it mostly occurs in the morning, but the situation starts improving after the 3rd month of pregnancy. However, it is a very individual symptom.
Hair and birth problems
Some people believe if a woman cuts her hair during the pregnancy the baby may have vision problems. It is difficult to explain this superstition from the biological point of view as there are no evidences which would support this theory. What is more controversial is whether women should dye their hair while being pregnant. The use of hair dyes has not been definitively linked to birth problems, though experts advise to refrain from this procedure in the first trimester.
