After having that dark OPK`s 2 days unfortunately we couldnt do anything!

My last BD was 3 days before O. We have several kiosks in a mall and DH has been working since friday with our employess.(you know how crazy is it after thanksgiving!) He came home like dead and couldnt even hold his arm, he was willing to try last night but i just didnt want it b/c he was extremely tired.
Anyways, i am so sad right now. It has been long cycle and i have been doing OPK`s and charting for 30 days and just O`ed. That is so bad not to bd on+opk day.What do you think my chances?it is really low isnt it?
My temp went up a bit today, i think it corfims i O`ed. Last night at 8pm my OPK was still +.I think I 0`ed after midnight..I dont have anymore OPK to test.. i guess it wont matter if we bd tonight or not.what do you think?
