17 days past ovulation.... need some words of encouragement Pls

I'm about 17 days past ovulation and no AF. I've been having some pregnancy symptoms, cramping, more discharge, boobs tender. I've taken tests and all coming out negative. My last test was This last Friday: it's now Sunday. Idk what's going on here. If it's my period why can't it just come down already and stop giving me hope I'm pregnant :( I just wanna know already!!
