Pregnant???

I haven't missed my period yet but I've had nausea In the morning food cravings and dislikes to foods I normally eat. I have been feeling like crap the past couple of days and had spotting. Also I'm constipated. 
I'd be super stocked if I am 😍. We've had tried all this month so could I be pregnant and have symptoms before missed period? 
27 years old trying to have first child. First time trying. Please give me some advice thanks!!
