TTC any chance ?

I’ve been testing since last week Tuesday/Wednesday. My period is due this Wednesday. I’ve gotten all negatives, clear blue digital, and pregmate sticks, first response early detection. I got a faint positive on a regular clear blue but idk if it’s an indent or not. Is there any chance I might be pregnant at all if I retest when my period is due. I have on and off nausea & cramping. I want to be pregnant so bad. I took the one with a faint positive on Saturday. I took a first response one today but there is no line 🥲
