early symptoms?

Yesterday at work I felt light headed and dizzy all day and I fell out in the parking lot skinning up my knee and ankle.. I don't fall unless I had too many shots of tequila but since I was at work and have been trying to conceive I have to believe this is symptomatic.. I also have been sensitive to touch of my nipples and smelling chewing tobacco.. I just ovulated on the 20th is this too soon to be having these symptoms? I swear I'm not going to pee on another stick til New Year's eve! Anyone else with me?
