5 weeks 3 days cramps

I have been cramping on and off since before I found out I was pregnant. It isn’t painful, but it feels like pms cramps. Is this normal? I havent spotted or bled. I dont “feel” pregnant yet. I al not really nauseous, I did feel a little dizzy a few days ago but it stopped. Boobs stopped hurting. I still feel very tired. Is it normal for symptoms to come and go?!
