Period late 2 days

My last period was on the 27 of last month and lasted until the first (which is normal for me) my period has been on time, the exact day that glow says i start and i haven’t started. I had sex during my fertile window, I have sore breasts off and on and I’ve been using the bathroom more. I’ve had little pains in my stomach, could I be pregnant? I’ve taken a test two faint lines on clear blue but took pink dye (days before my period was actually due) and got negatives. Should I wait and take or test or should I go ahead and do it? This would be my first pregnancy.
