Pregnant after having 2nd child in march2016

ja
Had my son March of this year...found out I was pregnant in June I'm now 12 weeks.... I will be doing this alone again! I was NOT trying to conceive... I made my first doctors appointment this week it's at the end of the month. I was going to have an abortion but when I finally got the money together (I would be 13 weeks when procedure done) I reconsider. This will be my 3rd child, when I told him he said it wasn't his lol haven't heard from him since smh.. All three of them are his.im very overwhelmed and stressed still looking for work my mom is helping with bills. How can I afford another one? I'm phlebotomist tech and is hard to find work in my city! Lord give me strength and guidance
