I need help

まち

Okay so, ever since I transitioned to being vegetarian, I haven’t been getting my period regularly, and sometimes, I skip a month. I don’t know why either, I mean, yea, I’m not getting protein, but why does it affect my period? And I don’t want to eat meat again because every time I do, I get really sick! So I mean, what is wrong with me? 😂 I’m legit confused and trying to laugh this off....
