I have irregular periods and am 17 DPO positive Clear Blue Digital Ovulation Test. I am 3 days late for AF per my most recent cycle length. I haven't have any other signs of pregnancy except fatigue today and the discharge in this photo. I've had negative FRER tests the past 7 mornings including today. In the past I've had back pain and cramps in the days leading up to AF. I haven't had any cramping in the past few days.
