Too tired - peak day

I'm at peak fertility today (wed) and the hubby is too tired! Arghhhhh 
We BD last night (tue) (high reading on OPK) and before I had 3 days worth of low readings. 
Last time we BD before last night was sat. (Low reading) 
Hubby says we can do it tomorrow - is that too late or is there still a chance this month?
