Hgg levels?

I’ve currently found out I’m pregnant. My last period was on the 21st-25th December. I did a test on the 13th January which said 2-3 weeks. I’ve been for a blood test today and my results were 409 hgg… is this normal for only 5-6 weeks? I have to go again to get them done tomorrow to see if my levels have doubled but I just need some reassurance of what a 409 may mean so early on? Any ideas??
