Does anyone ever wonder about that? We have been timing bd around my temp rise--some combination of the 4 days before and day of. And we tend to stop right after that for about a week. Does anyone else ever wonder if that is a problem? What if my body is a little different and this timing is actually preventing pregnancy. I know that sounds ridiculous. I do know of one couple who tried for 2 years and then finally threw out the temp chart and opks and just dtd every other day all month long. That is the month they got preg. Just a coincidence? Anyone here get pregnant with different timing?
