Do I have a chance ?

My husband went away for a work trip tonight and won’t be back for 4 days…. We managed to BD tonight. My OPKs are getting darker but looks like I won’t get my peak until tomorrow so ovulation day will be Monday (calendar photo below is incorrect). Do I still have a chance ? The only other BD time we got in was 4 days ago which feels too far from ovulation to really be of any benefit.
