Help Please!! Letrazole vs Clomid?

Has anyone's doctor prescribed them Letrazole instead of clomid? My doctor said that is my next step starting with my next cycle. I told her I was surprised because I was expecting to hear Clomid and she said that Letrazole is kind of like the 'new clomid' and I was wondering if anyone else has tried it or had success stories or any helpful information to share? -- TTC #1 for 11 months with crazy irregular periods 🤷🏼‍♀️
