Wow, that's confusing! You had an ultrasound that showed a sac as 5 weeks 3 days and now they can not find it at all? How long ago was the scan that showed the sac? The body 'can' absorb it or it can break down but it wouldn't happen over night. Do you still have pregnancy symptoms? Do you still get a positive pregnancy test? And they made sure there wasn't anything going on in your tube like an ectopic, right?
That definitely sounds very strange sweetie. You've not had bleeding or anything in which anything was expelled, right? so, that would be crazy for it to just be gone. Yes, that is unsettling but I would think at this point that it is a mistake. So, you go next week? That will feel like forever to wait--- but please let me know what he doctor says!!!
Absolutely you can and should hope! I will do the same for you!! hugs
