How far along would you think?

I know that I won’t really know for sure until my first ultrasound, however I have semi-irregular cycles. A few months I may have a 28-30 day cycle other months it could be 40-50days. My last period was July 14th, putting me at 5 weeks 3 days. I got my first faintest of faint positives on August 13th, had my first blood draw on the 17th and my levels were only 66.99 and my re check on the 19th came back at 126.73. I’m just wondering if anyone had similar levels and how far you were at those readings?
