Abnormal sac BUT baby has strong heartbeat

Lisa
Im obviously terrified to go to the bathroom throughout the day everyday now. I went to the er for two small blood clots. No bleeding or cramping since. Its been 2 days now. The dr said My hormones are high and baby has strong heart beat BUT Abnormal Sac . I am also 6 weeks and 5 days. I googled abnormal sac and have read nothing but negative results as far as miscarriage coming soon. Please tell me your experience if youve had one similar to mine. This is my first pregnancy and I have been trying for 3 yrs now.
