Having kids in your 30s

Alana • I`m 30 and realized that I want to start a family sooner than later. I`m trying FAM for next year until we get started.
How is it that all these years I hear, "you are too young for babies, don't rush". Then most of my 20s I didn't have any of my shit together enough to conscientiously have a baby. Then I meet someone well suited enough for procreation, we enjoy a few years together in the blink of an eye I'm of a "higher maternal age" wtf Mother Nature?? We are living longer and waiting to have families for a multitude of reasons.
Sorry venting about literature considering me an old woman. Are the early 30's seriously too old have a first child? What is the ideal window? 22-26????!
