Is this a positive OPK??? help!

Dr
Hubby and I did the BD yesterday morning at 9:30 If this is positive, (I think it is but I just want to double check just in case) should we BD tonight or tomorrow morning? 
I know sperm needs time to replenish and an OPK means you'll be ovulating in the next 12-36 hours so I'm just confused as to what the best optimal time would be. Please please help this is our last cycle to try for a long long time.
