Bleeding 5 - 6 days after ovulation? Today I had blood on my undies, could it be implantation? I had a smiley face on my Ovulation test on the 13th, that same day I had intense cramps.

I didn’t test days before I got the smiley so not sure how long I have had the smiley for but the same night I got the smiley I didn’t have it during the night. Only in the morning . Now I’m experiencing spotting , what could this be???
