Uh oh😶😶

I'm currently 17 with a 3 and 1/2 month old son. Me and my fiance have been together since I was 15. We've lived together for almost a year now and I love our little family. I took a pregnancy test last night because I had been light headed lately as I was with my first. Found out this morning I'm pregnant again. I'm so excited but also worried. I should of went to our 6 week appointment. I don't know how my fiance is gonna feel, it's already hard for us now with my part time job and his 2 jobs. I guess the few times we had some fun was too much fun.
