Confused and need help?

So on Christmas I found out that I’m pregnant. This is unexpected to me because me and my husband were not planning on having kids until 2 years from now. Our living situation and financial situation is not stable. We live with my family and with a lot of cats and dog in the house. It’s a scary experience because we dont know what to do. A part of us is for abortion because its stressful environment we are in. My oldest sister is pregnant and have a 6 month old baby that my mom already taking care of and I dont want to burden her even more. But a part of us know if we go through abortion there’s always a what if and how things will turn out. It’s a sense of regret, if we had our own place and finacially stable maybe the decision will be easier.
