Hcg levels

Hey ladies

So according to glow I am 5 weeks and 3 days pregnant.

I was meant to get my period on 5th of December, didn’t get it and took a test on the 6th and 7th and it was negative.

On the 10th i took a test and it was positive, but it was quite light, not faint but not as dark as I expected.

The next day I got a blood test and today I received the results of the HCG only being 30. Tomorrow I will be going in for another blood test

Is this normal? Any advice

I’m just stressing myself out right now. I know I just have to wait to see what happens..

Thanks in advance
