Is it just me or is our youth having to early?

Looking at all these pregnancy questions I notice way too many young teenagers asking if theyt are pregnant. They are worried and scared and obviously not ready to be parents. It scares me how many young ppl are having and hoe young they are. Im only 22 so its not like im too far from their generation and im not a church girl. I just think that if your going to have with someone the tought of getting pregnant shouldn't worry you. I didn't wait till i was married to start having but when ever i thought i might be pregnant my partner and I (now my husband of 2 years) were excited and verry happy to bring a child into the world. I am 22 weeks with our first child. And I am so scared of how life is going to be when she gets older.
