Not sure if this is implantation blood. Let me know what u think. I’ve been using the Clearblue Advanced digital ovulation tests since December 20 2018. I got my first flashing smiley face December 21 and I still have them to this date. I got this bleeding yesterday one I the morning (2nd picture ) and one in the afternoon (3rd picture).Also today at 1:20 pm this bleeding (4th picture).
