Actually research shows that young mothers are at the same level as older mothers after 10 years, they usually get stepfathers to raise the children and experience the same income/education.
Additionally regarding "finding yourself" or "developing into yourself" you will never reach a point in your life where you are finished exploring the infinite ways to exist, places to live, ways to behave, so going down that road is an endless journey until your biology tells you to get pregnant or you accidentally get pregnant. It's a stupid concept invented by a new society. Our ancestors didn't try and discover themselves, they existed, had sex, had children.
Virgins arent having children because of abortion and birth control, but that's defying biology, and not for the better. It means sex is now no longer a biological precusor to having children, having a family, becoming responsible, becoming independent, becoming man and woman. It's now masturbation with another person, that occasionally leads to pregnancy that is ended by medical intervention. All the purpose of sex is removed and you're left with some sad co-masturbation ritual.
Live according to nature, the stoics figured that out long ago. They were happy and healthy. What is society today? Miserable and unhealthy.
