Scared

So last night I went to the ER my hcg levels suggest I'm 5 weeks pregnant but they did a transvaginal ultrasound and the radiologist says he sees a true sac but it's only measuring 3 weeks but the ob said what he sees looks more like a pseudo sac which would suggest an ectopic pregnancy. I go Tuesday to see if my hcg levels went up by at least 65% if they did then that's a good sign the pregnancy is growing if not chances are indeed it's ectopic I'm so worried and scared 😞 anyone else experience this? Or have any success stories?
