According to what you've told us, you ovulated, at the most, 9 days ago. You wouldn't be feeling nausea quite yet, or experiencing frequent urination. It sounds like because you want to be pregnant, you're noticing all these things now. It's very common when one is trying to conceive.
Try to relax these next few days, and take a pregnancy test when your period is due. And don't feel discouraged if you're not pregnant yet - it takes a healthy couple an average of a year to conceive. Good luck!
