Had an oops and now uncertain what's next

My husband and I recently found out were pregnant. Not something we planned seeing as we use contraceptives and preventatives. We are struggle with what to do next. Financially we make enough to pay the bills, but not anything extra. We battle back and forth on what we should do. Right now it's us struggling with this battle we haven't shared the news yet. I always wanted this to be a happy experience, but since it was a HUGE surprise I am anything but. I could use some help.
