Pregnancy chances?

My fiancé and I are starting to try for a family. And at one point we were pretty sure we were pregnant but think we may have miscarried very early on. Long story short, as you can imagine, we were both devastated. Now this cycle we had sex on day 21, 25(OVULATION DAY 🥳) and 26. What are my chances of pregnancy this month? Any tips for getting pregnant from other mamas or any advice? I could use it all ♥️ Thank you!!
