Help,?

💗louise💗 UK • Mummy to 1 prince and 2 princesses 💙💗💗 pregnant with our 4th little one our 2nd boy 🥰💙👶🏻 due January 2020
Morning ladies, what will be my main fertile day from this pic. I'm at the end of my period and now just spotting so it should stop later today. Added pic of my calendar so what day in the green? Or shall I just do it everyday? Saying that my partner is only home until Tuesday 31st. But I have heard sperm can live for a few days. What do you think my chances will be? Thanks
