OPK help

Sasoli

Hopefully someone can give me some insight. This is 3rd month TTC, 1st month using OPKs. I've had flashing smileys for 4 days now but no solid ones. According to Glow the big day should have been yesterday. Did I miss it? Is glow just off? I have tracked my cycle on glow for all 3 months, just nothing else. So confused. Update #2: more BBT chart. 10 days of flashing. Keep thinking I should stop for this round, but then I see people that o'ed

late in the game. Anyone who's used these know if it will go back to blank if levels drop or just flash forever? 😓
