AF was due 9/24. I tested for the first time at 13 DPO and got the result in the first pic. I tested again the next day and it was darker. I started bleeding and cramping today (5 days after my missed period) and took another test. The line is barely there :/

I think I did have some blood in my urine when I tested today, so is it possible it got diluted for the test or is this most likely a chemical? Does ovulation usually get pushed back for the next cycle? Has anyone conceived the next month after a chemical?
