I’m at a loss.

A little bit about me. I’m married to my wonderful husband. We have 3 kids together, a daughter who will turn 3 in December and twin girls who JUST turned 5 months old. We live in a 3 bedroom house with one bathroom. We are currently living paycheck to paycheck to get by. And I just got a faint positive pregnancy test. Before any judgments come my way, I can’t be on birth control due to the negative effects it has on my body, and my husband has a vasectomy planned. I’m not someone to abort a baby, it is not the right choice for me, I would not be able to live with myself if I did that. That being said, I’m so scared, I’m sooo terrified. We were not planning on having more. It is completely our fault for not being 100% careful before his vasectomy. But I’m struggling. What can we do? I’m a stay at home mom because daycare alone would take my entire check. Are there any types of work from home jobs I can do? Any and every piece of advice would help me. We are keeping this baby I just need some advice on how to get through everything. My husband just got a second job and should be making some more so that will help a little.
