Sorry, I probably didn't explain myself very well!

If you ovulated on the 10th, then today you would only be 10 days past ovulation. It would be very early for pregnancy symptoms even if they started today (and you said they started 11 days ago).

An embryo does not implant until 7 days past ovulation at the earliest. Then it takes another two or three days to start excreting HCG (the hormone which causes many pg symptoms) into your blood stream.

Hopefully, that makes more sense!!
