Oh sorry to hear that. But thank you for the advice:)
I've been trying for a year and a half and have recently been diagnosed with PCOS, which makes it extremely difficult to get pregnant ):
Buy an ovulation kit. It's just like pregnancy tests, but it's to tell your most fertile days. And it's more accurate that trying to guess when it is. But the more sex, the better in those few days. Even do it twice a day if possible.
