I need help

Glow said my af was supposed to start on the 8th and it didn't. But according to a couple websites that I went to, they said my AF should start on the 16th. My hubby said my areolas are a little bit darker than usual, I'm bloated and when I get AF, I don't bloat at all really. I've been nauseous and badly fatigued, my mood swings r nuts lol I'm gonna take a test on in 2 days if AF doesn't come sooner. Who thinks I might be pregnant?
