Hcg & 10dpo

Hello I told my doctor I was pregnant getting faint line because I’ve had 4 miscarriage. And I haven’t missed my period yet I am suppose to miss it Friday. My doctor ordered a blood drawn and my levels came back at 35.6 for 10 dpo. And she messaged me today which I am 11 dpo to repeat blood tomorrow and that it seems a little low. I thought that level was great at 10 dpo 4 days early for my period. Suggestions? Anybody have the same kind of story and everything come out good.

UPDATE *****

In two days it went up times 5. It went up to 179.9 at 3w 6d
