Hello i had spotting for a week after i found out i was preg had ultra sound nothing to early to see had bloods hcg only rose from 661 to 753 progesterone level 10 could it be a miscarriage doctor said suspected on the phone have more tests tomorrow thank

Yes: Beta-HCG levels are expected to double every 48-hours in early pregnancy. Failure to double especially in the context of vaginal bleeding suggests a nonviable pregnancy which is most often from a miscarriage. These are more common than anyone realizes; in fact half of all pregnancies miscarry and are often never even detected. Don't distress, but do continue with your scheduled follow-up tests.
