How many days to have sex on the window?

Katie • Stay at home mommy as of 6/30/16!!!
So what do you recommend? My fertle window started fri and we had sex nothing on Saturday then we had sex Sunday (18 or 19 %) mon (28% according to glow) Tuesday they say maximize chances (23%) today wed is (7%) but my husbands body is starting to get burned out doing it day after day. Should we skip and hope and pray we got something on the other days and hope glow isn't wrong on my days? Or BD one last time which we might struggle if our body's are tired. Trying to get this bc we've been trying for 10 months now I hate to have another let down.
