So I'm 18 DPO and on 12 DPO with 2 days to spare until AF I got super light spotting, like just a dot of pink. At 13 DPO it turned to a dark brown and was just slightly heavier. I had that until yesterday which was 17 DPO. I'm not sure if it was implantation or a light cycle. So I took a test today on the off chance it was implantation, and I wasn't feeling well this morning. This is not FMU. So Not sure if I see an evap, or a very very very faint line on the bottom test. I know for sure in person there is something super light. It's harder to tell in the pic.
