Being confused and TTC

So Glow was telling me my most fertile days were from 10/11 - 10/18. Peak day was on 10/15. Now when I go on other sites they're telling me my most fertile days were from 10/12- 10/22. This is where I really start to have doubts because from 10/18- 10/22 hubby and I didn't BD. Hopefully I get my BFP this month even though I have doubts. I was thinking about taking a test since AF is due 10/30, that way if I don't get my BFP I can start preparing for next month. Baby Dust.✨
