Light AF

Just wondering if anyone else had experienced this. After coming off the Nuva Ring, my first AF is very light, to almost spotting. I was supposed o out the ring back in on the 22nd of Sept. but we wanted to start TTC so I didn't. Tested with a hpt on the 8th, 9th, 11th and 12th and got BFN. Here is my chart. The two days not charted recently in the pic have green check marks.
