Thankful for my infertility

Any one else ever find themselves being thankful you can't get pregnant easily? I'm 20 and have been careless about protection since I started having sex 4 years ago and I've actively ttc'd for about 2 total years of that. And I'm realizing how much of a mistake it would have been to have a baby at any time during those 4 years. I wasn't ready, I wouldn't have been a good mother the person who would've been the dad wouldn't of been a good dad. I'm just thankful that I didn't end up putting a baby I didn't deserve into such a bad situation.
