Hi Frank. Some of mine took 3 weeks or more to germinate. So, I probably wouldn't be too worried, yet.

Frank, pull one seed up and squeeze it to see if it's rotted. You may have over-watered. I recall just planting mine in damp mix and then just misting them instead of watering them.

Or it's possible they're still in the process of germinating. It can take up to twenty days or so. Good luck!
