Pregnancy Levels

So I had my bloods done on 13DPO and it came back 46iu/L and the fertility clinic said that it’s normal for an early pregnancy and blood results but her voice made my anxiety go through the roof... has anyone had their levels be the same at 13dpo and gone on to have a healthy pregnancy? I have to retest on Monday which will be 7 days after my first lot of bloods. Baby Dust 💖
