Help!!

So I’ve been so extremely tired and I’ve been really moody and shit and there’s been light cramping once in a while. Last night I very suddenly was hit with the feeling of being so extremely hungry. I had just eaten 4 hours prior and wasn’t able to even think about food without gagging for a solid 2-3 hours after. And during the super hungry period, nothing sounded good except for plumeria which was the only thing I could eat last time I was pregnant while feeling like that. My tests arrive tomorrow from amazon and I plan on testing Sunday. However I’m probably only 3-1 today and will be 3-3 then. Is it too soon o feel symptoms? I know it’ll be early for testing but I have to once it it’ll kill me.
