Teen Mother And Worried

Hey my name is jenna and im really skared that I might be pregnant but it wouldnt really bother me that I was its just that if I am I would be raising it by my self un till the father got out of his 15 month program and im not sure what to but I know that he would be there for me cuz ive been with him for 14 months already and it was his idea to get pregnant but I just wish he would have waited to get me pregnant untill he got out of his program but im gunna find out if I am in like 5 days but im already like a week after my period but im still worried cuz my mom would kick me out if I was but he didnt pull out when we did it so I guess im gunna be a only mother for a while and thats really skary what should I do?
