Should I test again?

AF was supposed to arrive a week ago and nothing came. I usually have severe cramps and nausea with AF, but I’ve had no symptoms except for being slightly more emotional/cranky. I took a test the day after I missed and it was negative, but it’s been over a week and still nothing. I’ve been TTC since August and am sick of getting negatives, but is it worth it to try again or should I just wait for AF to show up?
