CD43 14days late so frustrated

Amber
Blood test NEGATIVE :( HPT Negative :( I'm have pelvic pain (mild cramping) that comes & goes no sign of AF! My cervix is high I would say medium & closed. I'm just so frustrated this has never happened to me (Missing AF) like if I'm not pregnant cool AF come on but if I am then I need a Positive HPT. I haven't stressed out or changed my diet so I don't know the cause. Last week I think I had ovulation pains but idk. I just have no answers :(
