Trying, I've been at it now for 7 months for my third. Had one at 26, 2nd at 29. I know how you feel. Try preseed - very sperm friendly -could be your cervical fluid isn't sperm friendly. I am also using soft cups to keep the swimmers up there (also called instead cups). Using instead cups means you don't have to sit there with your feet in the air for 20 minutes after. Try early pregnancy tests.com and order a semen analysis, so you know where you stand. If you've tried for months after this, go get your hormones levels checked to see if everything is the way it should be. Are you using opk's? Comid is good stuff- usually a couple of months and you're pregnant.
