Just hormones?

Im 6 weeks pregnant and god everything has been annoying the crap outta me my childs father is so annoying to me like i don't want him touching me or even trying to kiss me. Another thing i feel so unhappy i feel like I've just ruined my life im 17 and I'm pregnant with my second child my son is 2 he's perfect and healthy and well taken care of before anyone wants to talk crap about that. I just feel like im having a baby with the wrong person if that makes sense? I don't know how to explain i just feel like I've ruined everything
