I just wrote you a long post and lost it - ugh...
I am so sorry that you are going through this difficult time. I know it is just horrible to get through. There is a possibility that you miscarried a twin. There is also the possibility that you miscarried and then conceived shortly afterwards and that explains the low hcg levels. Some women have miscarried without even knowing it. The tissue dissolves and then they later have a heavier period. The best thing to do here is to continue to have your hcg levels monitored and have some ultrasounds every one to two weeks to see what is going on. You were so early when you were first diagnosed. I think a D&C at 4 wks is just horrible! In the first trimester there are so many variables that can affect diagnosis. That is why it is wise to test out what is going on. As long as there is no fever or hemorrage, you can even have a natural miscarriage if that is what is going on. Hcg levels are not always accurate indicators of what is going on although they can signal problems. Another thing, what was the mhz of the u/s machine, skill of the tech, position of the uterus, age of the machine? These are all things that can affect u/s readings. My husband had a u/s done on his kidney. The tech couldn't find his kidney. It turned out that she used too high of a mhz to find it! The tech used a 12 mhz and should have used a 3.5 mhz. Different levels are used to find different organs depending upon their location. How much more so with a little embryo!
I hope that you get some definite answers. Let us know how you are doing.
