early pregnancy symptoms

TTC for 4 months, I'm 5 dpo and just curious of what some different early symptoms are.  I've had extremely sensitive and sore breast, get nauseous randomly throughout the day, a lot of bloating which isn't normal for me even during my period, very mild cramping and have had an increased amount of discharge. We're trying for our first so I don't know if these could be symptoms or if it's just my mind playing tricks on me.
