Seriously though, it probably won't work past 6 months or so unless you're a bigger girl. You probably need your parents support whether you're keeping the baby or making an adoption plan. You don't deserve to go through this alone (and good for you not getting an abortion).
I'm sorry, I'm 14 and I have more sense than you. You can't give your baby away. The mother and new born have a special connection which no one can interrupt, it's a special feeling. This is your baby. Your special little human. You need to do the right thing. Your smart enough.
