Well me and my boyfriend haven't technically been trying to convince, but we have inter course with out any protection and he always comes inside me. This has been going on for about 13 months now & I haven't gotten pregnant. We have sex quite often too, I would say 73% of every month and nothing. Were not specifically trying like have the ovulation kits or any of that. I have the app pink pad and we used those fertile days as my ovulation dates although I'm sure they're not spot on my exact days. But we've done it all over, days of supposedly ovulation and not. & we still have no result.
