a boy or a girl?
1. Nub theory:The nub theory is basically about 'the angle of the dangle'. Between 11 and 14 weeks' gestation both genders have a penis-like protuberance between the legs. They look incredibly similar at this point, except for the angle at which they are pointing. A boy's 'dangle' is 30 degrees up relative to the backbone and a girl's is below 30 degrees.In order to be able to have any chance of predicting the gender, the foetus must not be curled up- they need to be lying as flat as possible. Also, it must be side on and apparently, it is better if the fetus is right side up.A scan at 12 weeks is around 75% accurate and at 13 weeks it's closer to 95% accurate.
2. A blood test that can reveal a baby's sex just seven weeks into pregnancy has been developed by doctors.The new test - which will cost around $500 checks for the male 'Y' chromosome from the unborn child's DNA which can be detected in the mother's blood. It has so far had a 98% success rate in trials.
3. Chinese calendar:It was originally used by Chinese royalty to help swell the ranks of male babies, thus ensuring the continuation of the royal line.Based on the Chinese Lunar calendar, the chart uses a combination of the mother's age at the time of conception and the month in which the baby is conceived to 'predict' whether the baby will be a boy or a girl.To use the Chinese Pregnancy Calendar you simply find your age at the time of conception, then trace along the corresponding line on the chart until you reach the month in which you conceived. If the corresponding square is pink it means - surprise surprise - that you're carrying a girl, while a blue square means your baby will be a boy.
4. Skull theory-looks to the shape of the fetal skull. Supposedly, boys have larger, blockier foreheads, while girls’ heads are rounder.
5. The baking soda test:this one works by testing the pH (acidity) of your urine. All you have to do is add a tablespoon or so of baking soda to your urine sample. If it fizzes and bubbles a lot, you are having a boy. If there is no reaction, you are having a girl.
6.Morning sickness theory- another popular myth regarding baby gender prediction has to do with morning sickness. They say that if you are having little to no morning sickness, it means boy. If you have a lot of morning sickness, it means girl.
7.The Cabbage Test — cut one red cabbage into chunks, boil for 10 minutes, then set aside. Head for the bathroom, and pee into a cup. In a separate cup, mix 1 part urine with 1 part cabbage water. If the water turns pink or red, this indicates boy. If the water is purple, it’s a girl.
8. An ultrasound is the most accurate way of determining the sex of your baby. The best time for the technician to see the baby's gender is between the 18th and 26th week.
There has been no scientific research done that shows any of these tests to be accurate, but they do have a large following of believers. Please, don't take it very seriously. You may not want to go painting the baby’s room blue or pink just yet!
