My last period was September 23rd. My cycles have been long since February around 35 to 40 days I missed a period in January and assumed I missed in October. I was tracking my ovulation starting what would be cd 10 of my cycle if I had gotten my period. I started getting high fertility on opk starting cd 13. I realized after I asked a question on her I shouldn’t be taking with fmu. The day I tested during the afternoon I got a peak on cd 24 I had been very lightly spotting 2 days before and 2 days after. Only when I wipe and very shear pink or even brown. Im now on cd 26 or 27 I believe. I took a test right now just cause I never ever spot and someone said maybe implantation. And this is the test. Obviously very faint if there is anything.
