You are pretty much far along enough to find out through ultra sound. They will do one at 20 weeks for sure

At 17 weeks, you should be able to have a gender scan with your doctor. The old wives tales aren't always accurate.
They are just for fun, but all of them have worked for me :)
Just read the other answers - do NOT put urine in with bleach. That creates a toxic fume! It is incredibly dangerous.
You put a little bit of baking soda in bottom of cup and pee on it...if it hardly does anything its a girl, if it fuzzes up like soda pop its a boy. It was right for me:)
