Hcg levels

Hello!

So I got my BFP yesterday 6/17 and I’m due for AF on 6/21. I got bloodwork done yesterday and the results came back today that my hcg is at 11. Please someone tell me that 11 is okay for only being 3w6d along?

My doctor wasn’t in the office today so all the nurse could do was tell me the results and that they’re low but that it could be because I’m so early. My doctor is AMAZING and I’m anxious for her to call me tomorrow but I’m having a hard time waiting.
