What were your early signs?

Courtney • Married to the love of my life and trying to conceive our one baby to complete our small yet mighty happy family. ❤️
I'm 2 days from my expected period and the last almost week I have been feeling a little bit abnormal. 
​Everything I eat gives me heartburn, and I have never had heartburn in my life. I've puked once or twice, which is also weird, because the rest of my day I can be fine and feel no stomach sickness at all. I also spotted only once a few days back. My CM is white and creamy also, and I'm a little bit emotionally unstable. 
​What were your early signs of pregnancy? And does this sound like it could mean a BFP to come?
