14dpo and have light pink and brown spotting

Since yesterday at 13dpo I have been having this very very light pink only when I wipe. Sometimes there is a little bit of brown spotting. I know brown means old. My boobs are not sore. I have very very very light cramps on and off. My period is due tomorrow. Today is 14dpo and its not getting heavier at all. These pictures is from right now. One wipe was very very light pink and the next wipe was this little speck of brown blood. Anybody had this happen and ended up with a bfp. I know pregnancy and period symptoms are very much alike. I have NEVER experienced discharge so pale pink before
