Am I out?

So AF is due in four days, according to Glow. During this whole TWW, my stomach has been feeling "off", like super sensitive and tender and likes there's pressure there and I've been having way more headaches than normal. About a week ago I had some light cramping, but it went away. Yesterday my boobs started to feel tender which normally doesn't happen before AF. I've been super emotional and sensitive all week. Just about ten minutes ago I had some light pink spotting, first time all day. I'm just wondering if I could still get my BFP this month or if it's probably just AF on her way? Anyone else experience this? Thanks!
