Im kinda confused myself, did i test too early?

What web-site told you you would ovulate on the 16th? If you used one of those "ovulation calculators" , well, those are about as accurate as throwing a dart at a calendar and seeing on which day it lands. The OPKs are way more accurate, but only show when your body is gearing up to ovulate...they can't say if you actually did or when. The ONLY way to know that you actually did ovulate ( and when) is my charting your basal temps. A really good site for charting them and learning more about your body is www.fertilityfriend.com (it's free too!). I always "thought" I ovulated around CD 14-16 and by charting I realized I actually don't ovulate until CD20.
