Er ultrasound can’t see the baby

Andressa

I went ER tonight cuz having light brownish discharge. She didn’t do vaginal ultrasound and she can’t see the baby or fetal pole. Believe I just turn 7 weeks of pregnancy today, also my hcg level is 529 which she’s said isn’t good enough. My last hcg level on Wednesday 20th was 489. I am so scared since I had a miscarriage in 2017. Is anyone go through related to my story. I am not sure what to think anymore...
