Pregnant and questioning

Hello, I’m 18 and I found out that im pregnant a few days ago, im already 6 weeks along and Im conflicted wether to keep it or not. I live by myself. And my bills are a little more than $2,000 a month. The father is undocumented and might be leaving the country soon so it’s just me. Im wondering what type of benefits I could receive from the government or any outside source if I decide to keep it. Or would it be entirely impossible for me to do it alone? :(
