I’m so confused

So I can’t remember when my last period was but for the past few weeks I feel like ive put on weight and have these weird cravings like chocolate melted on quavers and when I eat something I need more of it, I’m defo eating a lot more then I would and my partner noticed it aswell, I’ve took tests but all negative and I can’t even go to doctors as I’m not registered at any atm as just moved here😔 I’ve had this white watery lumpy discharge aswell, any ideas?
