Please help! CT SCAN!

Elizabeth

Hello all!

I need a cat scan done on my sinuses. I ovulated the 9th.. my period is due the 23rd. My cat scan is the 21st... if I would be pregnant do you think I'd be able to tell by then? I know they say 5 days sooner than you missed period but I do know a few people who didn't get positives till after they missed their period.. if I would be pregnant I'd obviously tell my Dr but isn't a CT Scan dangerous then?

Thank you!
