So I didn't have a period last month which was supposed to start on the 21 and after 13 days I started but it could be considered light. At the end of it I had what looked like brown and even an orange color for a few days. But the whole time in between I'm also had more back pain, sore breast and nausea. All negative test. So confused. I also drink and after a shot my stomach cramps really bad and my back too. I also have never been 13 days late 5 maybe but never that many.
