Children after 30

Hi all so im 26 M got married few months ago to wife 29F. We love each other deeply but due to logistical issues we couldn’t get married before but have done this year.

Now the issue is i keep getting told my wife is getting too old to have children. In our culture women usually have children early to mid 20s.

Now as a man i love her and will stick by her forever and ever. But i worry when i hear things like this because we plan to have 2/3 healthy children god willing. Maybe even more.

Im a simple man and i dont know alot about these things however Ive heard women giving birth well into their mid - late 30s.

Can any woman please share their experiences and help me understand if the noise people around me are making is nonsense. Thank you!
