No heartbeat 😩

Selina

So I’m freaking out right now .. had an er body due to sharp pains , comes to find out I have a UTI .. but they did an ultrasound and I’m suppose to be 7w 3days based on LMP but To them I measured 6w 1day and there was no heartbeat at all.. they did an abdominal ultrasound after they said they were going to do it vaginally but didn’t.. they want me to come back in 7 days for another ultrasound 😞 I’m just so scared at this point I thought the heart was suppose to be beating by 6weeks already.. have this happened to anyone but everything turned out okay at the next visit ? 🥺 they also tested my hcg levels and I think the number she said was 25,00 I’m not to sure I was so tired from being in there from 8pm to 7am.
