pregnancy symptoms

So just found out I was pregnant. (We've been trying) my symptoms so far are having to pee more often, super mild cramps, a little dizziness. That's it. My boobs aren't sore at all, but my husband told me they look a little fuller. 
Is it normal to not have sore boobs right now? I'm only 4 weeks
