Have you had very light spotting and late af right before a bfp?

2 days before af, i noticed very light pink when i wiped after bd. The next day, when i used the restroom, i had white discharge with very little pink and spotted very very light brown only when wiping. On the day of af, again, only very light brown spotting. This is now cycle day 2 and still the same, very light brown spotting when i wipe.

I'll test after work today it af doesnt come...but have u had pink or brown spotting days before af and when af was due, you continued spotting and eventually got your bfp?

I'm still getting period like cramps, lower back very sore, and only my left breast and nip are tender.
