but I think it's more a case of people being able to answer why some women are IF and that women are starting later in life to ttc.
For instance, my paternal grandmother didn't have children right away and then after her first, there was a 5yr gap and then two one after the other. So who knows why she had troubles, people didn't go see a Dr about that stuff back in those days (1916/1921/1922)
I thought when I started to ttc at age 29, I was young but by some standards, I was already over the hill. I still think it was young
I am now 42, not ttc (btw). I am a lurker who doesn't quite know the definition of lurking since I speak up sometimes LOL
