Best friend being pushy about my pregnancy

So I’m 21 weeks pregnant, this will be my first child after several miscarriages. I’m in my 30s and happily married.

I’ve had the same best friend since high school, and we always used to joke that she would be the first one to get married and have kids as I was pretty socially awkward, but things didn’t work out that way. She’s in a 6 year long relationship with someone who she knows isn’t the one but she’s afraid to leave. Anyway, she’s become pushy regarding my pregnancy. First she was pushing for us to do a gender reveal and actually got annoyed when we didn’t, like she tried to make invites and everything. She took it upon herself to start my registry and start buying my baby stuff? She then was trying to plan a baby shower in which I would fly to her (we live in different states). I turned all of this down, I don’t like attention and I just want to relax and not do any of that. He newest thing is pushing for me to take photos of my belly every few weeks because she’s convinced I’ll “regret it” if I don’t. Once again I’m not sentimental, I’m not going to miss my belly, as at that point my little boy will be here. I’m about ready to just cut the friendship off. I’ve mentioned several times now in a nice way that she’s being too pushy and to let me live my life and handle my pregnancy as I would like but she always has something to say. Any advice?
