I don’t know what to say

A girl I went to high school with is telling me Im so lucky to have the happiness of being pregnant and having a child, but yet she already has 3 beautiful happy, healthy daughters. She’s upset with me because her boyfriend/3rd baby daddy had decided he doesn’t want anymore kids. Like what am I supposed to do here? She also sent me a pregnancy test that was clearly negative but she said the watermark on it was a faint positive. Now she thinks shes having a miscarriage. And won’t listen to anything I have to say about it just being in her head. Mind you I haven’t spoken to this girl in 10 years. So her messaging me in the first place was weird to me.
