Why???

13 DPO, 4 days late and still BFN! :( I’ve been nauseous and bloated for the past week and keep crying over everything. (I am not a crying kind of person) I used cheap tests first day late and nothing so yesterday I went and got the nicer brand and tested with morning pee. Still this result (below)

Why oh why??!? Has anyone else experienced this? Could AF just be really late or my BFP be coming in just days?

How long should I wait to retest? I’m tired of being so disappoint d :(
