*A little descriptive tmi* So I posted yesterday but adding on... today makes my period 6 days late. Yesterday morning with fmu I got a negative on a test. In the afternoon I had a small amount of bright pink spotting. Today the spotting is a little more, not a period flow but enough to wear a panty liner. Should I just consider this my period? My body is like clockwork to the day, it's not common for me to even be a day late.
