Sometimes squash gets going a bit slow and it will seem like you have tons of blooms but no squash forming. One year I went for weeks on end with no signs of squash, and then finally toward the middle of the growing season, squash showed up almost overnight and I had a great harvest.
Check on the ground underneath your plant, make sure the fruit aren't falling off before they get a chance to ripen.
If you don't see any fruit (or large amounts of blooms) on the ground, double-check your light and water situation. Squash need full sun and plenty of moisture to thrive. And you will need patience as you wait for your fruit to appear!
