AF is 6 days late not normal for me she usually shows right up. Took a test on 3 days late got negative took a test today negative as well then while at work I noticed brown discharge/cm and I was very tired to the point where I left early went pee again and a little more brown discharge but none after that and my nipples are kinda sensitive but not a lot.. taking another test if AF doesn't come by Saturday then making an appointment for Monday with OB.. but what are you guys' thoughts? THANKS IN ADVANCE 💕
