Preg? CM? Ovulation test.

So I took a ovukation test on Halloween.
         Got the smilie face, had clear egg white CM. Then today (nov2) I was feeling funny. And took another ovukation test. Came back smiling aswell. But today I have little CM and it's white and creamy. 
       Is it possible that the test is just picking up the egg even though it's in the process of making a baby?
 Or is it common for you to get pregant 2-3 days after sex with ovulation. accruing?
