OK so are you financially able to support a child for 18 years? Do you have medical insurance if you live in the U.S.? Does it cover maternity care? Is your mother willing to watch a baby while you work? If not, who would? If you go on to date someone else, would your mother watch a baby while you stay overnight at your boyfriend's house? Will your job cover an extra $100 a week, which is what a baby costs? Can you work and live on your own?
What happens if you get sick? Who would watch the baby then?
Personally, you should see a doctor and get tested for STIs, since you weren't using condoms.
BTW, you're not a breeding dog that has to have a child and give it up to others. There's no reason why you should have to be pregnant for nine months because someone else 'might' want to adopt a newborn.
