So fed up- mother forcing names on me

Basically I'm 25 weeks pregnant with my rainbow baby

I lost my baby boy last year ( Ruben )

and I'm due Christmas Day.

Me and my fiancé both love the name Cora even before I was pregnant this time.. and when we looked up the meaning it was perfect and we knew it was the one ( meaning : filled heart)

I've told my mother what we will call her and she's doesn't like it, and ever since she's been texting me names she likes and asking if I like them. When my mind is already made up.

I hate that she's trying to control me and name my baby.. she had her choice naming me.

She's texted me names like- mila, molly, indie, sylvie and loads more.

I don't know what to do, it's putting me in a bad mood as me and my fiancé love the name

We have chose.

Help.
