Transvaginal ultrasound

El

I went to the ER yesterday because I have a upper respiratory infection. So they wanted t check on baby okay cool. I got a US & I’m measuring 5w4d I thought I was at least 6 weeks lol. Well theirs a fetal pole present and that’s it US tech did not seem too worried but when the physician came back in she kept rambling on about the fetus still may be in my tube so basically she’s saying I could still be having a ectopic pregnancy but it’s too early to rule out. I have no history of them & my pole is in a great place. I feel fine 🤷🏽‍♀️ so with that being said is this all normal? At my gestation only a fetal pole?
