For a woman is 26 too old to date and marry?

I want to have 4 kids that’s my target, 5 max although.

I have heard of women 30 struggling to have kids all the time but also a girl that is 26 who miscarries a lot.

I am 26 what girl should I aim for as I want to date for a year then marry.
Why do people struggle so much these days?

Aim for 20
21-22
23-24
25-26
