Is this positive ovulation strip? It's super late for me to ovulate and I don't usually test at midnight but I felt lower abdominal soreness so I did this. It's CD15 for me and when I conceived 2x this year (ended in miscarriage) I ovulated like day 11/12... I didn't test cd11 but I did on cd12,cd13,cd14 all negative... Ughhhh I bd on cd8,cd10,cd11. :( did I miss our window?
