I need some encouragement please. 5 weeks 1 day pregnant

I’m having no symptoms. I got my blood drawn Wednesday at 4 weeks 6 days and it came back 405. I’m supposed to have another blood draw tomorrow but my lack of symptoms is making me nervous. Like I feel fine. I almost would say I feel better now than I usually did before I got pregnant. Not to mention the people at my dr keep mentioning that my levels need to double before they’ll make me an apt which I understand but they have repeated that quite a few times without me asking about an appointment. Almost like they think I’ll miscarry? My last pregnancy was successful and my levels at the exact same time were only in the 200s but I think I had symptoms and now that I don’t I am worrying
