Exactly this. It's vanishingly rare for a woman to get pregnant NATURALLY over 46-47, and as I said, the suggestion that's it's common and easy is misleading and cruel. Because it's giving women hope. Even 43-44 y.o. women are unlikely to get pregnant naturally. Sure it can happen and it does occasionally, but it's not COMMON.
Even though people don't like to hear this on here, the fact is that once women pass their mid 30s, their fertility start to decline, and with each passing year it declines further and further, and quicker and quicker... Yes women get pregnant naturally at 35-36+, but it becomes more difficult to conceive naturally after your mid 30s.
I am sick of seeing posts on here where people claim to know many women who had babies NATURALLY after their early 40s, with no complications, smooth pregnancy, easy birth, and nothing at all went wrong.
A woman who has passed her early 40s, who has a natural conception, a smooth pregnancy, and a complication free birth is in a very small minority.
