signs or not?

ok this is gunna be long……about 3 dpo started noticing small things. bbs felt "heavy, light nausea, ect…ect…figured it’s natural because my and my b/f had had unprotected sex right around or on my o date and people get "signs"……as time passes I’ve noticed more…all of a sudden I have a quite amusing road map on my chest blue veins everywhere and they just keep appearing out of nowhere. cramping,bachaches,maybe sensitivity to smell….not sure if it’s in my head or not..tested from tuesday to today all bfn but not due to get af till tomorrow…..feel like shes coming but not sure…what do you think? Please let me know…I’m rather worried.
