Been thinking about your post, did your doc ask you to have your HCG monitored? you can find out if everything is ok, or go and get a dating scan next week or 2. If you have your HCG monitored for a week to see how its doubling (blood test every 3 days) then you can tell if the pregnancy is going ok. Also progesterone levels can indicate a progressive pregnancy also. Can you ask for these tests to be done?
