Confused

Sh

Please give me your advice! I don’t know if I’m thinking too much of this or what. My RE said I can’t proceed with this cycle because my lining is too thick(16mm). But I’m wondering how it is going to work because after this AF ends my lining will grow some more until the next AF comes. At that point won’t it still be too thick?! How am I ever going to have a lining that is thin enough? I’m so confused 🤷🏻‍♀️ 🤯🤔
