Grinding my gears

I’m currently 12 weeks pregnant, when I first found out I told my mother and she called me a dickhead because me and my partner we are planning a wedding which is booked for July 2020 so I said it’s fine both can be done.

Since I have got pregnant my mother has distance herself from me, bearing in mind we was close before now all she does is ring and when she asks how I am and I say it’s back ache or I feel sick she tells me to get over it I’m only pregnant, or she says I give it an hour and half before you ring me and want me in the delivery room when your in labour which upsets my fiancé because he wants it just to be us two when I’m in labour (never been pregnant before so how do I know what it feels like)

My brother and his fiancée have just had their baby which makes it my mums first grandchild she’s going over on Sunday for the day with my sister never invites me just said I you can’t go your working but if i don’t go over I’m still the bad one for not making an effort (my brother lives a 4 hour drive away)

Am I being a drama queen or is my mother being horrible?

I just don’t know what to do atm every time she rings I don’t wanna answers it because I come off the phone so mad at her
