Is it too early? is it all in my head?

I am 2DPO and I have a runny nose (which isn't common for me), I am and have been gassy for 4+ days, last night I had cramps (that felt as bad as gas cramps), I've been having really weird and distinctive dreams, I have been waking up at night for the past three nights with the back of my shirt soak and wet from sweating while sleeping, I have a mild breakout on my chin, I've been tired on and off during the day, with weird boosts of energy in between. Am I going crazy? Is it too early to be having symptoms. (Also, this is our first month trying, and I am not sure when my last period was last month, and the only was I know I was ovulating is because i took a test and it showed I was ovulating). Please help. I need sanity.
