Have you read the shettles method? he does make reference to concieving with mitteshmerz. try charting your temps and see when it comes in relation to your spike and whether it occurs at the same time as O and if it does then that is you best time. you can also concieve up to 3 days before O as the sperm do survive. have a look in the gender swaying section and you may find more info on shettles method.
