This is a question we see a lot so it must be fairly common. 5 wks is still really early. I would not yet be concerned about not being able to see the sac. Your HCG is also within a range that is included for 5 weeks of pregnancy. So I don't see a reason to be concerned there either. They often do a follow up HCG to see if that number is increasing. Did your doctor schedule that? What did your doctor say? From my perspective, I'd follow up with your doctor and obviously do another HCG and ultrasound to check on things but would not stress at this point! Good luck and let us know how it goes. How are you feeling? Any pregnancy symptom?
Oh my gosh, so confusing! Your hCG levels almost doubled! In what time frame between tests did that happen? Is that typical of a corpus luteum cyst? Sure, it can produce hCG but following along the same kind of path with pregnancy increasing like that? And you CAN be pregnant and have the cyst at the same time. Anyway, I guess you know that this *could* be the cyst but it also may not be. And your doctors have to understand why you'd feel that way and they too should continue to monitor this. Do you have another ultrasound scheduled at 7 or 8 weeks? By then, you can often hear the heart beat and all so that will be much more telling. But I'm sorry that it is so confusing and hope that your doctors are treating you with gentleness during this time. Please let me know what happens next. hugs
