Hi!  I should have gotten my period 8/31 and it didn't come. I am usually right on time. Tested Thursday (8/31), 9/1, 9/2, and 9/3 and they were all negative. Yesterday afternoon I got this, which I *thought* was a very faint line. I tested again this morning thinking that would give me a for sure positive and it looked negative. I have been nauseous since Thursday and a little sick in the mornings. A few minutes ago I went to the restroom and had some spotting. Can't tell yet if it is just spotting or the start of my period. Any insights are appreciated!
