am I pregnant?

Paislie • 27. Dog Momma. 🐶❤️
I am now 3 days late, which I've never been before. I've been having tender breasts, cramps, headaches & backaches. You know, the usual leading up to a period. Today I thought I had started but turns out it was just very light/faint brown discharge, I've also been having white/watery discharge these past 3 days as well. Will I start my period soon or is it a possibility I might be pregnant? I have taken 2 tests and they were both negative. I figured it was too early to tell. Any advice/comments?
Thanks!
