Hoping I'm just an oddball

Not likely but here's the verdict . I started cramping about 7dpo with milky cm and pinching pain in my side then at 9dpo I had light pink spotting . My nipples are hurting so bad , not really my breast but my nipples . AF is due today but nothing no sign of cramps or anything but yesterday I had a Bfn . I'm hoping I'm just gonna be the one who unexplainabley test negative until like 20dpo . Trying to wait until monday to retest . I know I ovulated two weeks ago !! Why would I not have my period ? Or am I miss understanding something . Can you ovulate and not have a period ? My temps have been raised .
