Pregnancy ? Or period ?

Hello ladies ! So I'm 3 days late on my period which never had happened before , I'm always right on the money with my period. I've been eating alot or I don't eat at all , I get headaches super easy , and my boobs are super achy lately & also my nipples have been getting dry which never happens either ? Another thing is I'm getting extra "wet" these past couple of days , I always have to rush to the restroom because I think I've started my period but when I look I see it's only wetness . I've never had this problem , I only usually get wet when turned on . Could this be a possibility of pregnancy ? I'm still cramping but nothing yet. If you ladies could please help me out I would greatly appreciate it !
