20 years old & pregnant with baby #2

I need help & advice. I currently have a 6 month old son & just figured out I’m pregnant with number 2 (which was not planned at allll) I’m so scared & terrified & don’t know what to do. Does anyone else have 2 babies under the age of 2? What’s your advice? I’m just so lost right now. (Also the baby father & I are not together.)
