2WW is terrible!

I am in my 2 WW and I am going crazy. AF is due on Monday, but I can't help but take test, I know it's early but I can't help it. I am having symptoms so I figured why not! I am nauseous every morning no matter what I eat or drink, my boobs are sore and appear swollen, I am getting mild cramps mostly on my right side, I am always tired And I am having very vivid dreams that I am pregnant. Third one this week. It felt so real that I had to wake up and thought that I was really pregnant only to pee on a test and have it be negative. It makes me so sad!!
