no, 9 days sounds way too soon. Really though, it depends on your ovulation schedule. I would wait until after you know you've missed your period and then test. Or wait 3 weeks after having the sex you believe could have conceived the baby.
If you missed your period saturday, you should be able to test now and get accurate results. I understand about wanting to wait, though.
And yes, sounds like this could be your month! Hope you've got a bun in your oven!!!! :)
