Symptoms

Got my positive at 4 weeks. My boobs hurt really bad, I had to pee A LOT, I was hungry 30 minutes after eating. I’m 5 weeks now my boobs hurt but only a little bit, I have cramps almost constantly sometimes they feel like my period but most of the time they are a lot lighter than that, my mouth is super watery, my boobs are bigger, and I’m really warm but I go from too hot to too cold and it’s super annoying, and I’m still hungry like all the time. Is this normal or am I experiencing these symptoms too early? My periods are all screwed up sometimes I won’t have one for months. I started my last period September 14th and it was not a normal one it was super heavy and I had terrible cramps and it ended kind of early. I’m just confused this is my first one.
