Need advice on when to have sex- peak fertility with OPK

Nancy
My obgyn told us to have sex every other day (husbands count is slightly below normal range). Well, we did it last night around 11:30pm and this morning when I took my Clear blue digital test, I got peak fertility (solid smiley face). I never got the high fertility (flashing smiley), just got peak. Today is day 17 of my cycle and I average at about 31-33 days. 
Not sure if we should do it again today or if we should wait until tomorrow. Anyone have any recommendations? Thanks!!! 😊
