sister pregnancies

Simplified story: my sister is 5 years older than me, when I got eloped a year ago she had nothing to say to me not even congratulations due to a fight we got in months ago. Now we're pregnant at the same time (she's one month ahead) and I've tried to use this experience to mend the bridge and reach out to her but whenever I ask her about baby names or the baby moving she just shoots me down and refused to tell me the name she picked, I already knew what name she picked but I wanted to talk to her about something she'd be excited about. She told my mom that I never ask her how she's feeling or how she is but at least I'm making an effort to connect, she doesn't reach out at all. And she said she feels like I'm trying to make our pregnancy a competition? Just wish being pregnant at the same time as my sister was as fun as I thought it was gonna be
