Lightest line ever? Flashing smiley also


I’m only on cd 18. I could’ve O’d super early but I’m not sure when I did. I had some EWCM and solid smiley on cd12. I re checked my OPK after the solid smiley went off bc it seemed weird to me to Ovulate that early. I’m still getting a flashing smiley for the past 4 days. See anything on my frer? Think the flashing smiley is just rising estrogen after Ovulation? The only reason I’m texting early is bc I have a procedure scheduled on Wednesday.
