You should use condoms/birth control if you are not in a position to have a child.
The word is pregnant. Writing it wrong makes it sound like you are incredibly young, in which case you need to take some serious thought as to how you will care for this human. How will you give it the best life possible? This isn't 'fun' this is someone's LIFE you are thinking would be 'neat' to go through with.
How do you support yourself? Do you have a job? Health insurance? How much do babies cost? How much does rent cost? Are you aware that in addition to rent, you have to pay for electricity, phone, water, sewer, garbage, and that doesn't even include food or diapers.
Does your boyfriend plan on quitting school and working full time to support you and the baby? Do either of you know how much daycare costs?
Get some birth control.
