Am I pregnant....

Im 6 days from my period. Took a first response early test this morning, not with morning pee cause I woke up at 4am to pee...half asleep not thinking. it was a BFN. symptoms are head aches. a little nausea. tender breasts..mildness. I got a uti from all the baby dancing we did during ovulation. Slight twinges in the right side of my uterus. I feel like im pregnant, but it could just be in my mind...lol. Do you think I should test again or count myself out for this month and try again next month?
