On Thursday of last week I started spotting I was exactly 5 weeks then. I left work went to the emergency room and there they did a urine test and a vaginal ultrasound . I was told that I was threatening a miscarriage and my hcg levels were 1400. On yesterday I had my first prenatal appointment were I was given a urine test and blood work was done. I’m going back to see the OB on the 15 for a ultrasound then I will be 6 weeks and like 3 days.So on yesterday which was Monday I made it to work and blood was pouring out of me. I went back to the emergency room and blood work was done a ultrasound and urine test everything was fine and my hcg levels went up to 3500. But they did not see the yolk sac on the ultrasound. Has any other ladies experience this.
