I was diagnosed with unexplained fertility after 3 years and I have two children conceived in the usual way

although our doctors went through chapter and verse of our sex life, explained it was important to have sex outside the fertile window as well. I suspect, based on what jade has shared, they were only having sex in her fertile window. Your fertile window can change month to month and you really have to be watching your body closely for signs of ovulation.
Thank you for attending my biology Ted talk
