Sorry hun. I think with another blood test and another u/s they'll, and you, will know more. I will say that if you are actually over 6 weeks, they should have seen something there. Again, sorry. Not knowing exactly what's going on is awful.
Well your levels are supposed to double about every 2 days. Did they see the gestational sac again? I hope they are going to repeat your bloodwork. That will probably tell you a little better if your levels are rising even more. Sorry you have to go through this. Good luck.
