I have had 2 miscarriages in a row late 2014. The first miscarriage there was no sack or baby and the second was only the sac no baby. I calculated that i am about 9 weeks. I started spotting mostly brownish so i went to the er. They did an ultrasound and blood work. They saw a baby on the ultrasound but it measured 5 weeks 5 days and no heartbeat. The blood work said my hcg levels were 5344 which she said would be around 3-5 weeks. The lady said there might not have been a heartbeat because it only measured 5 weeks. Im so scared i dont want to lose another baby i really hope everything is ok! :'(
