During pregnancy, everyone from family members, friends and even the lady at the grocery store will tell you what the gender of your baby is...and give you a great explanation behind their choice. Whether it is a lucky guess, old wives tale or a watered-down fact, these explanations are fun and exciting for the mom-to-be. Remember that no matter what the guess, however, you still have a 50 percent chance of carrying a baby boy.
Many games insist they can predict the gender. Add your age (at the time of conception) and the number of the month in which you conceived. If it is an even number, start buying blue. Another predictor is the Chinese lunar calendar, easily found on the Internet, which charts the mom's lunar age and the month of conception. The meeting point will tell you the sex of the baby.
The most factual way to determine if you are having a boy is via tests conducted by your doctor. Prenatal tests performed in the first trimester include an amniocentesis or chorionic villus sampling (CVS) test can tell you the sex of your baby. A less evasive way is to have an ultrasound, where the doctor can get an image of your baby to determine the sex. However, if your baby has its legs close to its stomach, has hands blocking the pelvic area or is turned the wrong way, its gender will still be a mystery.
