Holding onto hope

Am

I'm supposed to be 11wks tomorrow 💔 but last week at my first ultrasound they found a sac for 7w3days the sac was measuring perfect according my ovulation date but they couldn't find the baby or the heart beat.

I'm supposed to go back in on Tuesday, to see if they can see the baby if not they want my to terminate the pregnany, this last week has been extremely hard for .. I holding onto hope that theirs some kind of miracle that the baby was just small .. But on the other side I feel as if it won't be like that I'm so exhausted fighting with my heart I feel so lost that I'm not sure how I feel or how to react, ttc for 2yrs finally pregnant just to find out the sac is growing but no baby , I duno how to over come this 😔😪
