Need advice.

so I'm 40w 3d and this baby is due any day now. but I have a problem it's my mother.....since I told her I was pregnant she's taken it upon herself to tell all her side of the family before I managed to tell my 6 siblings ( she's my adoptive mum my 6 siblings arnt hers ) about my pregnancy even though I told her not too, she posted it to Facebook even though I told her not too. when I asked her to be in the delivery room with me she immediately told me that shed be the one cutting the cord not my baby's dad and that she will hold the baby straight after me not my baby's dad. I told her absolutely not he will cut cord and he will hold his child after me. she was not happy about that but then when I went on to tell her that my MIL will be taking me up to the hospital not her because the MIL lives closer and can get to me quicker then my mum can she hit the roof. anyway she seemed to have got over this but I find out yesterday that she has invited my father to be inn the room when I give birth which is something I do not want. now I'm pissed I no longer want her there at all but don't know if that is a bitchy thing to do, I just feel that with her controlling ways she'll ruin the whole thing for me and my partner and I don't want the birth to be ruined by her. any advice on what I can do??
