OPKs help! Which one is darker?

Sa

Hi everyone. I’m trying to discern if I DTD on the right days. Day 13 AM OPK was negative. However, Day 13 PM was positive (maybe a little light?). Day 14 looks deffo positive. Can you tell me if the surge was Day 13 or Day 14? I DTD noon day 14, so not sure if I missed the egg if Day 13 PM

was the surge 😭.

Which is darker?

Day 13 (pm)

Day 14 (am) ?
