AF is due today but I'm not having my normal PMS symptoms. I am having a little abdominal discomfort (assuming this may be cramps) my breasts are not sore, my low back is just fine, but I have random bouts of dizziness. I've had some pink/brown spotting. I'm not sure if AF will show today but I also don't want to waste a test. Should I wait until tomorrow to test or do it today?
