Ttc baby 3

Im soooo confused?!! I feel like garbage my breasts are killing me. Non stop mild cramping. Little bit of pink discharge yesterday. Im soooo uncomfortable. Keep taking test its not pregnant. Tested xmas eve still not pregnant. I ovulated 12/12. Im on day 29. Period is scheduled for 12/26. What’s happening here? And i usually have 27 day cycle. Am i still in the game???? Im i testing too early? This just doesn’t feel like period to me. Any experience would be great.
