OPK Dilemma!!

Jen • 37 years old. PCOS. Daughter born 5/25/17 after beating infertility! 💜 Daughter #2 born 3/21/2019. 🎉

Do any of these look positive? I know they are all dry except for the last one. I assumed the top was + until I saw no fade progression. I also had brown ewcm on Friday (top test) so thought it might be a sign of ovulation. I need help. Any thoughts??
