How did you determine when you ovulated (meaning: what method did you use)?

And what was your intercourse timing like?

Right now-based on the info you gave- you are only 10 DPO (days past ovulation).  So in another four days (unless you know already your luteal phase length) a home pregnancy test would be accurate (if you get an early testing one that should give you an accurate result as well).
