Ugh! This question should never, ever be asked.
I can't count the number of friends that I have that have had struggles with infertility, miscarriages, and even stillbirths. So very sad.
And KSU- 35 is fine. I was almost 34 with the first one and almost 36 with the second. Both totally healthy kids and completely healthy pregnancies.
(and I had a blast in my 20s 
)
