Help needed


So can anybody explain this to me went to the er today cause my cramps were out of this world I️ told them that I️ve been getting positive test so they did a urine sample no blood work and also a ultrasound this was the test but they’re saying it’s negative I’m a little confused now because as you can clearly see the other line? Ultrasound came back fine they said and if anything on this app it’s says I’m 5 weeks exactly
