There are as many old wives' tales about pregnancy as there are days a baby can be born. Here are 10 of the best ones:
- If, when you suspend and swing a gold ring over a pregnant belly, it moves side to side, it's a boy. If it moves in a circle, it's a girl [source: WebMD]. (This one is told either way, actually.)
- If the fetal heart rate is above 140 beats per minute (bpm), it's a girl. If it's below 140 bpm, it's a boy. (Actually, the baby's heart rate fluctuates throughout the pregnancy, and the rate is unrelated to gender [source: KidsHealth].)
- While a pregnant woman should not handle Drano at all, if someone else wants to, the myth goes: If you pour Drano into a pregnant woman's urine and it turns green, brown, black or blue, it's a boy; if it turns red or yellow or there's no color change, it's a girl [source: LTK].
- A woman who gets prettier while pregnant is carrying a boy; a woman who gets uglier is having a girl. (The idea appears to be that the girl is stealing some of the mother's beauty [source: WebMD].)
- If the father gains weight during the gestation period, it's a girl [source: IntelliGender].
- If a woman gets more acne with the pregnancy, it's a girl [source: IntelliGender].
- When a pregnant woman dreams about cigars or snakes, she's carrying a boy; if she dreams of keyholes and Vogue, it's a girl (well, obviously) [source: IntelliGender].
- If there's no first-trimester morning sickness, it's a boy [source: IntelliGender].
- If the linea nigra (a dark line that often appears running up the center of a pregnant belly) stops at the belly button, it's a girl; if it extends to the rib cage, it's a boy [source: WebMD].
- If the left breast grows larger than the right breast, it's a girl [source: IntelliGender].
While none of these methods is going to predict a baby's gender with anything greater than 50/50 accuracy, it can be fun to experiment. The only fool-proof way to know the gender of a fetus is via amniocentesis or ultrasound.
And even ultrasound can fail if the fetus has his or her legs crossed.
