It would really depend on the circumstances, not just the age. What are your beliefs about abortion, adoption and teen parenthood? What kind of support system do you have? What other problems, if any, are you dealing with? Do you have a good understanding of the challenges parenthood brings and what you’ll need to give up?
So, imagining if I’d gotten pregnant at 15:
a) I am strongly opposed to abortion, so that would’ve been off the table. My Mom gave up a baby for adoption before she had me, so I might have followed her lead. However, she did find it emotionally tough to do so, and I would too. By that age, I also knew I wanted to be a mom at some point, but didn’t know if I could, so I’d probably have been worried that if I gave up the baby I might never have another one. Plus, I’m white, and sad to say, white babies are more likely to get adopted, so my baby would probably have had good prospects if I put them up for adoption. (Unless the father was another race, of course.)
b) I had a pretty good support system. My parents are very supportive and would have backed me up whatever my choice, and I know I could’ve turned to my Mom for help parenting. However, both my parents were working then, so I’d have had to quit school. Not as big a deal for me as for most people, though, because I’d been homeschooled from grades 7–9 and would go on to be homeschooled for 11–12, so I’d have gotten grade 12 anyway.
c) I’m high functioning autistic and an abuse survivor, so those would have been challenges. At 15, I was having a flare-up of my PTSD because of the stress of being back in school, so I would have had a lot of trouble handling stress. Plus, I had no intention of having sex with anyone (I’m sex-repulsed asexual) so if I’d gotten pregnant it would probably have been by rape, which would have made it a lot harder to cope. (I did have several close calls at 15, where I had to threaten guys with the police to stop them from trying to sexually assault me.)
d) I had a younger brother (8 years younger) and had read a lot about child development so I had some idea of what babies needed, but I really would have had no idea what being responsible for a child every day would have meant. I would have had a huge learning curve if I decided to keep the child. I recently (at age 26) got a puppy and it really took me by surprise just how exhausting it is to have some vulnerable and dependent creature constantly seeking attention from you.
I honestly don’t know what I’d have chosen. Not abortion, obviously, but would I have kept the baby or given them up? I don’t know.
