is this normal?

Okay so ever since I found out I was pregnant I'd get cramps like the starting four weeks I'd get cramps all the time and I'd pee a lot and also feel tired. I'm six weeks now haven't been to my first doctors appointment yet. And I'm getting scared because I haven't been showing at all. (Only just bloated) and I haven't been feeling really much of any symptoms Is something wrong or am I tripping?
