How will i know the gender of my baby?

Ultrasound by 18 wks: If you can't waite until the birth, you may be lucky enough to see it during a routine ultrasound, often done around 18-20 wks. It is not a 100% that the ultrasound tech person can tell you during this procedure--baby may not be willing to show. There are places offering 3-d ultrasound with dvd/video recording for a nominal fee. No doctor-order needed. Congrats and good luck.

ULTRASOUND: Not sure what you are asking but typically if you cannot wait to find out the gender of your baby you can ask during your ultrasound. They will look for this and tell you if you ask. Is this what you mean? Only other way is amniocentesis reserved for older pregnant moms and other problematic issues.
