Is it normal that now I’m carrying his child I’m really possessive over the guy?

We aren’t exclusive or anything I just got pregnant after the fourth time of having sex with him. He’s handling it well but is it normal I get really possesive now I never used to, if he goes out I’ll check who he’s been following and stuff because that’s my child’s kid? I know I haven’t had the child born but it’s still a weird feeling? But we aren’t offical and he hasn’t made it offical after me being pregnant but my emotions are all over the place
