Honestly, Twas, you really can't predict it.
I'm one of four girls - my mum was desperate for a boy. None of us are close to my parents or foster parents.
My sort-of DP (I'll call him DP for ease) is one of two, he has an older sister. His older sister has always lived closer to his parents, and has two children now - but DP has the far better relationship with his parents. They holiday together (with me) and go for lunch and go shopping and do sport. His sister visits once in a while, usually if she needs a favour or DP's parents have invited the family for dinner. His sister and their children are much, much closer to her husband's family, they see them frequently and moved to be closer to them.
There were some trying years between DP's parents and I (we got together at 17 and have been together for 8 years, although the last year has been... unique, so we did uni together, I moved in with his parents, we moved out together, we lived around the country, we lived abroad, etc). but I think of them as the closest thing to parents that I've ever had.
There's no guarantee, if you had a girl, that she'd like girly things, or feel particularly feminine, or want to go to lunch. There's nothing to say that she'll ever get pregnant or face sexism. There is also nothing to say that you won't have a boy who is interested in sexism, or has lots of children, or loves lunches. It's a personality thing and I don't think it's even more likely to get a girl who likes those things, at this stage - It's just pot luck.
Enjoy your pregnancy, and try not to worry about this.
