I am dying to find a symptom that differs from normal PMS. I am having lower back pain that I haven't had in a while. I didn't want to get out of bed for the past two mornings when before that I have been up and out by 9am. I just realized that I  have peed 5 times today and only drank 11 oz of coconut water. I am either 5 days or 13 days late. I have two different period trackers and I skipped a month a few months back so it's out of whack. But usually I start on one of the apps. I took a test when I was officially late on both apps and it was negative. I'm waiting to see if it doesn't come by next Saturday (3 weeks) then I'm making a doctor appt. What do you all think. I'm not trying to get pregnant so I don't think I'm doing it to myself.
