An ultrasound is the most reliable non-invasive way to predict the gender of your unborn baby. An amniocentesis is almost foolproof, but is invasive and poses a risk to you and your baby. However, there are a great number of unscientific methods of predicting the sex of your baby that do not require a doctor at all.

One of the most common is the Drano pee test. A pregnant woman mixes her urine with crystal Drano (not the liquid version). The color of the mixture indicates the gender of the baby. Brown means that a girl is on the way and blue means that you have conceived a baby boy. Another easy predictor is uses just your wedding ring. Tie a string to the ring and dangle it over your baby. If it swings back and forth like a clock pendulum, you are having a baby boy. If it goes in a circular motion, pull out your pink paint.

There is one method of unscientific gender prediction that requires a little assistance from your caregiver. The next time someone listens to your baby’s heart rate, ask for the results. Anything above 140 beats per minute is thought to be a girl. Trying to predict the gender of your baby is one of the most enjoyable parts of your pregnancy. Dads-to-be and everyone else will quickly join in on the fun.
