Any input would help put my mind at ease. Thank you 💖

So I was having abdominal pain last couple days gotten worse so went to er today because my first appt isn't untill Dec 10 they did the pregnancy test I already knew I was Prego and they did blood work said everything looks fine then did a vaginal ultrasound and Dr said they see no fetal pole so my question is . Is 6 weeks Prego to early to see anything there is a gestational sac & yolk sac though .

To anyone reading this thanks for reading and I would appreciate some input so I'm not constantly freaking out. Thanks again 💖💓
