Maybe a good idea after all

So my SO stated that, we should have sex all month long, to conceive. But not including the Af day's. I told him maybe that's a good idea. My fertile window started the 12th, I received my positive opk at 12:56am. We have until the 31sy for a break. But i was thinking too, that we can get tired of each other, and not want to be intimate with one another. What do you think?
