Teen Mom...?

So, I need really good advice.
I'm 18, my boyfriend and I live together, and I just got my GED. I was going to enroll in Esthetician school next week. I am also on birth control.
However, the doctor gave me antibiotics without warning me (I had to do my own research to find out too late) that they counter act the birth control. I am now pregnant, and we do not believe in abortion personally.
We live in a 4 bedroom house with 3 other roommates who go to a University and party every night, who obviously would not appreciate us bringing a baby in. We also receive food benefits. Neither of us have jobs, even though my boyfriend has applied to 20 different places over the course of 3 months. My moms been sending us money to pay bills with that we have to pay her back eventually.
I am very afraid and don't know what to do. We have an option to go back to our home town and live with either my mom or his until we are able to get back on our feet but everyone who has a baby there gets stuck, and it is NOT at all a nice town. Full of drugs and crack heads roaming everywhere. We are not completely opposed to adoption, we just want to know all of our options and listen to advice before making such an important permanent decision. It would be awful to give our baby up for adoption because we fear we don't have the finances and then 3 months later end up with a good steady income.
Please, all advice is welcome and appreciated.
