39+5 highly stressed out and hoping baby is late

So I live alone in another state. My mom decided to come visit me while baby is expected sometime this week. Thing is, she just doesn't want to listen to anything I'm saying, my SO really tries his best to make sure whatever I want for baby, I get but she wants to force some culture thing which will have us spending money traveling cross country so his family can come to my mom's house to visit baby once born. I'm just so fed up and praying baby comes later than expected and she just goes back to her house.

She's not allowing me to make any decision regarding my baby and this after a loss 9 years ago when my daughter stopped moving at 28 weeks and I had to have a c section to remove her. It's such an emotional time, my daughter was buried this week 9 years ago and I'm still dealing with those emotions. As my mother I thought she would be more on the supportive end as opposed to making things hard for my SO since I have so much support this time around. Someone help me... Im so sad and depressed.
