Is period like cramping normal in early pregnancy?

I’ve been cramping so much. It’s not painful and is mild cramping no blood or anything. But it’s uncomfortable and makes me worry. It feels like my period will start or something. I read cramping is normal bc the cervix is expanding but I asked a few people if they had it while pregnant and they all said no. As this is my first pregnancy I’m kinda terrified. I go to the doctor tomorrow so I will talk to her about it. In the mean time I need reassurance. I’m 5 weeks tomorrow. The cramping is quite often. Mostly if I’m sitting down. At work I’m on my feet all day and I felt little to no cramps, but once I got home and sat down they come on.
