pregnancy symptoms or not.

I usually get sore breast and I am always nauseous before my period. this is our first month ttc. the thing is I can't even tell if these could be early symptoms or not just because this is just how my body usually is. I should start my period either Tuesday 5/27 or Wednesday 5/28 but I don't feel any different. Does anyone usually have these same symptoms before af and if so did you notice any difference when you got pregnant. I took a test today which is kinda early I'm either 9 or 10 dpo and I got a bfn. so I'll wait till Monday to retest
