For me, it would not be the right thing, but you have to make a decision for you. If you are having doubts, please think seriously about it. It will affect you for life. Don't make a decision for other people. Make the decision based on you and only you. It's a life, in my opinion. There are wonderful families out there if you don't want to keep the baby. Regardless, do what is right for you, not someone else. It's not something that can be reversed.
No matter what you do, we support you.
