Emerald Star~ I have been thinking of you these past few days.I really dont know too much to be honest.Your levels are great but if there is no sac on an u/s then it could be either of the 2 you said. Im soooo very sorry.This must be so hard to deal with.All the questions that must be in your thoughts!! Do let us know how you go.
Hopefully someone else on the forum might know more.Dont google too much either.You usually only ever hear the bad...trust me,i was on googling all the time and it caused me so much more worry than ease.
