I've been trying for my second child for two years and in the total 33 months I've tried for a baby (9 months with my first and 24 for a second) the only pregnancy I've ever had was my daughter. Never had a chemical pregnancy or anything. I've had investigations and the only thing they found was my progesterone is a little low but not terrible, and 6 months with Cyclogest hasn't helped so I don't know if that's the real problem or not. It seems to me that most people who share their infertility stories have at least one loss along the way, I don't read many like mine where there are no pregnancies. What I'm wondering is whether this gives any kind of clue as to the cause of infertility? Like if you aren't getting pregnant at all whatsoever but there are no problems showing up on tests, does this point to a different likely cause than for women who have early losses?
