Even if you reach that point, you're likely now at the age where fertility problems become a real issue.
If you want to have kids do it when you're in your early 20s.
This sort of "hurry up or it'll be too late" attitude is a great way to figure out that you don't want to have kids after it's too late to make that choice.
This is factually false :) and if you’re really worried, there are many options available to you to preserve what you will need or consider adoption - there are so many humans being born without a family after all.
