Could this miscarriage be true?

So my friend has a very big history of lying. She’s lied about stupid shit in the past and now I doubt everything she says to me which is such a shame. She’s now saying she’s pregnant, but today she’s been to the doctors and they’ve taken blood and told her she’s no longer pregnant? She hasn’t bled or anything but has been getting really bad pains in her belly and her vagina area so they’ve ran tests on her and will be giving her something to “flush the baby out” I think she would be like a month pregnant (if she actually is)

I’m just wondering if this could actually happen? She is my best friend but if she’s lied about something like this then I really don’t think I can be friends with her anymore. She knows I’ve been through some really bad stuff in regards to pregnancy’s so if she does lie about this then I’ll be done. 😔
