Ghost or Phantom Alarms

Has anyone solved this yet? I’ve had a phantom/ghost alarm for years now. I have an iPhone X that I bought when it came out and my ghost alarm has been happening since the first time I did an iOS update on this phone. It’s been years. I’m having a baby now and my partner hates it so much. Has anyone figured out how to stop this yet? It’s like I updated my iOS without deleting the alarms first and now they’re saved for all eternity. I read that someone bought a new phone and when they transferred their data over it transferred too. I cannot go on with this. It’s 10 alarms that go off every 30 mins, every single morning, and I can’t stop them. Please someone help!! Do I have to switch to an Android?! I don’t want to do that. Help. Me.
