Bleeding!!

So i took these test the first 2 Wednesday and the last blue one on friday! I was spotting so Thursday I went to the emergency room and was told based on the hormone levels i was at about 2-3 weeks cause i wasn’t showing on my ultrasound! Since Friday I have been bleeding like if it were my period and having cramps! I followed up friday for blood work and tuesday ill go in again for bloodwork and ill see my obyg on Wednesday? Has anyone gone thru this and still ended up being pregnant even with the bleeding?
