My Dr told me that in 48 hours the numbers should at least increase if not double if the pregnancy/baby is healthy. Thats all I have to keep me positive at the moment so I am hoping that this is right and that my numbers work out well.

How far apart are your tests? When is your next one?
ETA - Just saw your next test is on Monday - maybe go to the Dr tomorrow and request another one earlier, under the circumstances? It can't do any harm. Good Luck Hun and sticky sticky vibes.
