Itching and cramps?

I’m about 4.5 weeks according to the app. I’m 31 and this is my first time being pregnant. No nausea yet but I get really crampy every time I start walking around, which I have to at work unfortunately. They’re not unbearable cramps, just the dull achy ones in the lower abdomen, there’s no blood or anything. Also today I started getting really bad itching on my thighs.

Is all this normal stuff? I keep getting worried and am trying to do as little as possible at work, no heavy lifting, I’m a manager so I’m being extra bossy lol.

I am calling the doctor tomorrow to schedule an appointment, I’m not sure how far out the appointment will be because I work all day till Wednesday and go out of town Thursday and Friday, but a little piece of mind would be good!
