Over reacting or hormones?

So I don't have the most supporting group, not family, not friends. My boyfriend and I don't live together so I don't seem him as much since we have different schedules, and it just seems that every time I try to get close to him I push him away more. He still wants to go out and have fun and well I'm 14 weeks pregnant not to mention have 2 boys from previous marriage... Am I over reacting or just crazy hormones? I just feel like I literally have nobody. I have no person.
