I notice from your other posts that you're 15.
That means , for a start, that it's likely to be illegal for you to be having sex - potentially, your boyfriend could be charged with statutory rape (and pregnancy makes it pretty hard to try to pretend that sex hasn't happened).
Less than 6 months ago, you were posting about being worried about being sexually inexperienced, then you posted about having unsafe sex with this boyfriend, and now the two of you are planning a baby?
It may be time for a reality check here, I'm afraid. Do you know how you're going to manage school and childcare? Do you have the money for everything a baby needs? Do you have somewhere to live? Are your family going to be supportive? Do you have the emotional maturity to put another person's needs above your own for the next 20 years (at least)?
