Pls read!!!!! Need input

I have had some HCG AND progesterone testing and wondering if anyone has any input.

First HCG was 950, thought I was 6&3

Second HCG was 1567

Third was today at went to 2567,

I had an ultrasound and the dated me at 5&1, so a week off from what I thought.

I also had my progesterone tested and it was 29.2 nmol/l.

Just wondering if anyone has any insights? Similar stories?

Slow rising HCG’s and positive outcomes?

If it was ectopic would the US detect this?
