HCG levels..?

claire

So my app is predicting that I am three weeks and two days today. Oh I am supposed to get my period in six days and technically would be 8DPO today except that I have an IUD LOL. I’ve gotten 45 positive pregnancy tests and my digital one said not pregnant. I went in for a blood test today and my hCG level is 11.6 they want to retest in two days to see if it doubles obviously but for this early does 11.6 hCG sound OK?
