Suggestions appreciated

OK, ladies... I need input. I have been TTC for 15 unsuccessful months and 4 unsuccessful clomid cycles. I've heard from people that BDing every day is best, and some people that every other day is better. How do we keep missing the timing? I have confirmed O with strips and temping. (Posting last cycle charts to show you our BDing and my temps/OPKs)

Any suggestions are appreciated 💖 TIA
