How often we have sex? I'm on my 4th day of high fertility and this morning on a cheap-o ovulation kit the test line got noticeably darker than yesterday (but not quiet as dark as the control line). We BD'ed on Thursday, Saturday and Sunday. I have read every other day is fine, and I worry about putting too much pressure on my husband (and then him not finishing because of it) but don't want to miss my window. This is the first month I've actually caught when my "high" days are so I want to make use of it! 😝
