Nervous

Went to the doctor today to see how far along I am. Since I’m not really sure when I exactly got pregnant (long story) well the doctor did a vaginal and abdominal scan. She couldn’t see any with the vaginal scan. And she said she thinks she sees a sack with the abdominal scan. But can’t see if there’s anything inside. I have to see a specialist now to try to get a better scan. I’m just nervous that what if there isn’t a baby or something. I’m praying that I’m just so early in my pregnancy that it can’t be measured yet.
