ovulation in cd 20..

Lauren
Hey y'all,
I had a quick question! I ovulated on CD 20, I confirmed it wil BBT, so if we BD on CD19,20,21 and 22, what do y'all think my chances are? I feel as if that was far enough before for us to BD, just one day? I'm wondering if we didn't do it enough or if anyone has had luck with that one day before, and the day of and couple days after, or if that wasn't enough... ugh help this 2WW sucks 😂😂
