Could I be pregnant? We are trying to conceive?

My husband and I had sex every day from day 8 of my cycle to day 19 and I am 2 days late for my period and my breasts are tender and sore, I have been feeling nauseous in the evenings, my nose keeps running, my lower stomach hurts when I poop, I have had a little brown discharge but that's kinda normal, I have been having dizzy spells, and I seem a little bit more tired...I haven't been having any stress lately so that can't be why I'm late
