am I pregnant?

Diamond

Someone help!! I recently tested positive for a second pregnancy but I went today for a urine test and ultrasound and got weird results. Urine test, like the others came out positive...but during my ultrasound, nothing was found. I got bloodwork done and my HCG levels as of now are 944. my LMP was 1/14/2021. could I be pregnant or could this be an Ectopic Pregnancy?
