Yes you are definitely high risk .This pregnancy
is too early to be viable yet. You need another ultrasound
,2 weeks later as you have scheduled ,to determine whether the pregnancy is viable. By 6-7 weeks,the fetal heart beat should be present. I suggest that just wait for the ultrasound you have scheduled. The symptoms you have are common in pregnancy. Be careful though since you are at high risk for early pregnancy loss due to the fibroids,adenomyomas. If monitored carefully im sure you will have a successful pregnancy.
