HI Guys, Im new here and If anyone ever experienced this or have any insight, that would be awesome. Ive been tracking and TTC for 5 months. Im on my 6th month now and in the previous months I would spot brown 3 days after my fertile window ended up to the beginning of my period. this month nothing! which has me wondering if I actually did it this month. my period is due in 2 days and I tested today and got a BFN. Realistically, Am i out? or is it too early?
